Completely inert, non-magnetic, anti-microbial, and perfected for nearly every type of metal, ME-92 biochrome coating is highly versatile, lending itself well to applications outside of the medical realm. Here, we’ll explore how several other industries utilize ME-92 biochrome coatings to ensure safety, improve performance, and strengthen their bottom line.


Ensuring quality control and preventing metal failure across industries

The ME-92® biochrome coating is engineered to create a thin, protective surface layer that safeguards against metal failure and degradation. It offers customization options to fulfill the unique demands of various applications and industries, enhancing durability and performance across a broad spectrum of uses, including in:


A sector of the pharmaceutical industry, biotech involves the development, manufacturing, and commercialization of drugs used to combat a wide range of diseases and conditions, including cancer, autoimmune disorders, and genetic diseases. Like medicine, biotech is highly regulated, and it can take years, and significant capital, to bring a drug to market.

Bioprocessing equipment, including tubing, filtration systems, and other components, must withstand the harsh conditions of the manufacturing process. such as extreme temperatures, high pressures, and exposure to corrosive chemicals.

Food processing and packaging

Food processing and packaging involves the transformation of raw food materials into packaged, ready-to-eat or ready-to-cook food products. An essential aspect of the process is packaging, which protects food products from contamination and damage, helps to extend their shelf life, and provides important information to consumers about the product.

Some key processes include thermal processing, such as pasteurization and sterilization, and non-thermal processing, such as high-pressure processing, irradiation, and pulsed electric field processing. These processes require protecting machined packaging line components, stainless steel bearings, chutes, pumps, linear rails, heat seal jaws, and cutting tools from wear.

Research and testing laboratories

From autoclaves and fume hoods to pipettes and spatulas, stainless steel is commonly used for research and testing laboratory equipment due to its durability, corrosion resistance, and ease of cleaning. However, even bare stainless steel can’t escape the effects of repeated cycles of sterilization and use, making this equipment ideal for chromium coatings.

Pharmaceutical packaging

Stainless steel filling, capping, labeling, and inspection machines and components must be sterile and defect-free. These machines are designed to ensure gentle and accurate handling of the containers to prevent damage or contamination.


Designers engineer industrial robots to handle repetitive, precise, and sometimes hazardous tasks across manufacturing and industrial settings. These tasks include material assembly and handling, welding, painting, inspection and testing, and packaging, optimizing both efficiency and safety in these environments. From frames and sensors to effectors and grippers, industrial robots utilize a wide variety of stainless steel components subject to corrosive wear and metal failure.

Top quality control concerns biocompatible chromium coatings address

At the Armoloy Innovation Center in Dekalb, IL, metallurgical consultants aid in developing coating and plating solutions to meet strict regulations and quality control standards. From biotech to food processing and packaging, here are some of the top industry concerns biocompatible chromium coatings address.

Maintaining sterility

If you don’t use a biocompatible coating like ME-92® on stainless steel that undergoes frequent sterilization, sterilization agents and other harsh chemicals may cause it to corrode or deteriorate over time. This can result in a number of negative consequences, including:

    • Contamination risk. Corroded metal surfaces can harbor bacteria and other microorganisms that are difficult to remove during the sterilization process, which can increase the risk of infection and other complications.
    • Reduced durability. Without a protective coating, the metal surface may become pitted, cracked, or weakened, which can compromise its structural integrity and lifespan.
    • Reduced performance. Corrosion can directly impact the equipment and component functionality, leading to decreased efficacy or even device failure.
    • Increased costs. If the metal corrodes or deteriorates, it may need to be replaced more frequently, which can be costly in terms of time and money.

ME-92® coatings arrest corrosion from the following sterilization procedures: 

    • Steam Autoclave. This process involves placing the items to be sterilized in a sealed chamber and exposing them to steam under pressure for a specified period of time. The high temperature and pressure of the steam kill bacteria, viruses, and other microorganisms, ensuring the items are sterile and safe to use.
    • STERIS SYSTEM 1. Using a combination of chemicals and heat, the system provides a fast and effective way to sterilize equipment.
    • STERRAD Sterilization and STERIS EtO. Designed for equipment that can’t withstand the high temperature and moisture of traditional steam sterilization methods, STERRAD sterilization is a low-temperature technology that uses hydrogen peroxide gas plasma. STERIS EtO uses ethylene oxide gas, a highly effective sterilant that can penetrate most materials and kill microorganisms, including bacteria, viruses, and spores.
    • Gamma X Ray. The process involves exposing the items to be sterilized to a controlled dose of ionizing radiation, typically gamma rays generated from the decay of cobalt-60.
    • Bleach exposure, boiling, detergent scrubbing

Complying with safety and regulatory requirements

Adhering to regulatory safety and compliance requirements is essential for protecting public health and safety, and avoiding costly legal, financial, and reputational consequences.

Pharmaceutical packaging, food processing and packaging manufacturers, and biotech firms must comply with strict regulations and standards set by regulatory bodies such as the FDA and ISO. Robotics manufacturers and laboratories are also subject to a variety of regulations and standards, such as those set by OSHA, the EPA, and the FDA, and must ensure proper handling and disposal of hazardous materials, while also maintaining appropriate records and documentation.

ME-92® was the first chrome coating company to perform and pass the Tripartite Guidelines testing for biocompatibility. The current standard is ISO 10993, and ME-92® biocompatible chromium coatings have also successfully passed the requirements for biocompatibility to this standard and the following specifications:

Ensuring durability, compatibility, and reliability

Today, there is a clear need for clean, biocompatible coatings across a variety of industries. The thin deposit chrome coating applied by ME-92® addresses durability, compatibility, and reliability concerns with unparalleled performance and aesthetics.

Incorporating biocompatible chromium coatings early on in the product and packaging design phase is key. Packaging manufacturers, for example, are required to design packaging that is easy to use, transport, and store, while also being tamper-proof and child resistant. Robotics manufacturers need to develop products that can withstand the demands of various industries and applications — this includes designing robots that can operate in harsh environments and developing systems that can detect and prevent mechanical failures. Furthermore, all industries must ensure that their products can integrate with existing systems and equipment, such as production lines and machinery, to improve efficiency and productivity.

ME-92® biochrome coatings are compatible with nearly every base metal type, including aluminum (ALCOAT®), providing the following performance properties:

    • Arrests corrosion from sterilization, metallic debris, and particulate matter
    • Increases wear resistance and surface hardness
    • Eliminates galling, fretting, and spalling
    • Provides a hard, scratch-resistant, nonstick, smooth sliding, easy clean surface for a long-lasting, clean, and pristine appearance
    • Reduces high-intensity light reflection/refraction and glare
