Automation and Linear Motion Coatings
Armoloy coatings for linear motion applications reduce friction on bearing steels, enhance wear resistance, and extend operational efficiency.
smooth movement
The Advantages of Linear Motion Coatings
Armoloy specialized coatings are ideal for automation and linear motion applications requiring smooth movement over rolling surfaces. Armoloy’s corrosion resistance matches that of 440C stainless steel, making it a cost-effective alternative for linear motion components like guides and screws, offering a precise deposit thickness of .0001/.0002″,
Armoloy also ensures maintained machining tolerances and facilitates the smooth reassembly of linear motion components. Tested extensively, it outperforms hard chrome in corrosion and endurance by nearly 50%, simulating seven years of real-world use. Armoloy guarantees consistent, 100% coverage with a satin silver appearance, making it an optimal choice for linear guides, ball screws, and geared racks and pinions.
Linear Motion Coatings & Surface Treatments
By choosing Armoloy coatings, manufacturers can ensure that their components withstand the demanding conditions, resulting in smoother operation, reduced maintenance, and improved reliability.

Frequently Asked Questions
While thin dense chrome (TDC) and hard chrome are both considered functional coatings, TDC differs from traditional hard chrome in the thickness and surface texture. TDC coatings are in the range of 0.0001 to 0.0005”, while traditional hard chrome is usually over 0.002”, and can measure 0.010” or more, depending on the application. Because of the very low effective thickness, thin dense chrome can often be applied to existing designs without affecting tolerances or fit-up. In addition, traditional hard chrome has a microcracked surface while TDC has a micronodular surface. Both provide a low wear surface, but the micronodular texture can provide superior lubrication retention and wear resistance. Decorative chrome is another coating entirely and is actually a multilayer coating applied to provide an attractive, shiny surface with good corrosion resistance.
Certification to many industry and supplier specifications is available, including AMS 2438 and AMS 2460, depending on the location. In addition, the Armoloy network has fulfillment centers with Quality Management Systems accredited to NADCAP, ISO 9001, and AS9100 requirements.
The Armoloy TDC coating will achieve hardness values of up to 78Rc, with results ranging from 72 to 78Rc. Standard hard chrome typically ranges from 68 to 72Rc. The higher rate of hardness is due to the increased density of the coating and lack of a micro-cracked surface. The hardness of the coating is not as applied to the part surface. Due to its incredibly thin nature, hardness readings taken directly on part surfaces measure a combination of the coating and part surface hardness. Coating hardness must be measured on a specially prepared coupon and tested per ASTM E384.
