Inquiry (采购产品): Black Oxide We have a customer that is hesitant to use Black Oxide on a Driver with an internal spline. He is afraid it will add thickness and prevent the mating external spline from getting a proper fit. He is also afraid of "black material" coming off and getting into the transmission being tested. I need tech data about the process to convince him to allow us to use it on the first batch of 400 parts, with hundreds more to follow. **** Hidden Message ***** Greg Seaton 48150 Company: ATT E-mail: gseaton@assembly-testww.com **** Hidden Message ***** gseaton@assembly-testww.com
