The Science Behind Bi-Protec
The process of creating Bi-Protec starts by adding an initial layer of electroless nickel coating directly to the base metal at a thickness of .0002/.003″ (5.08/76.2µm) Once applied we then begin the plating process that adds an overlay of thin dense chrome —either our nodular TDC or XADC—at a deposit of 0001/.0005″ (2.54/12.7µm).
The overlay of thin dense chrome you choose will depend on the unique needs of both your metal surfaces and your industry. While both coatings provide enhancements to corrosion and wear resistance, Armoloy XADC proves especially useful for higher-wear applications. This is due to the addition of a synthetic diamond composite that increases hardness and thermal conduction abilities.
Regardless of the thin dense chrome chosen, Armoloy’s Hybrid Bi-Protec nickel chrome plating provides exceptional benefits for those with highly corrosive applications, including hard-to-plate metals. Capable of providing maximum corrosion protection and increased wear resistance—even in the harshest environments—Bi-Protec can ensure that high-precision applications avoid unplanned downtime.
