What is the surface treatment method for the rods of gas-springs?



(-----) 2007

I work for an manufacturing company which produce gas-springs products. In the past, this company used hard-chromium processes to coat the rod to reduce friction and improve wear resistance. Recently, because of the regulation, the company cannot further use the hard-chromium processes. Thus, we have to find another way to treat the rod of gas-springs. We know that many manufactured uses black nitriding to treat the rod. However, we don't know the detail of this process. Does this replacement process use black oxide after nitriding? Also, Could anyone tell us the seller of this equipment?

I think what you are looking for is salt bath nitriding, Srangsan.
