Electroplating
Electrolytic and Electroless Nickel
What are the main differences between electrolytic nickel and electroless nickel? Can one be substituted for the other in metal finishing?
Read MoreElectroless Chromium
I recently spoke with an individual who stated that there is an electroless chromium plating bath available. Can you give me any information on this bath? Is it commercially available?
Read MorePLATING BATH TITRATIONS
We have now installed a small on-site laboratory and have a technician determine concentrations and “add” for our plating baths and some of our cleaners. The problem we now have is this: He does not have enough time to complete the titrations and calculate the “adds” in a timely fashion. Do you have any suggestions on how we can improve this process and reduce the time requirements?
Read MoreHARD NICKEL
We plate sulfamate nickel on steel components to build up worn areas. Recently we have found that the nickel is very hard and almost impossible to machine properly. What might cause this problem?
Read MoreBLACKENING OF STAINLESS STEEL
We are looking for information on a simple process for blackening of Type 420 stainless steel needles. The blackening should be permanent, corrosion-resistant and medically acceptable. Since the needles are small in size, the method should be capable of processing in bulk.
Read MoreRUSTING PARTS
Our customer requires a steel part to be plated with both nickel (0.00015–0.00030 inch) and zinc (0.00025–0.00030 inch). The part is sterilized in an autoclave prior to use. Why is it rusting, and how do you suggest we solve this problem?
Read MorePAINT ADHESION ON STAINLESS STEEL
We use stainless steel fasteners that have to be painted after assembly. We have tried a number of different processes, but adhesion of the paint has been poor. We would prefer a black finish. Do you have any suggestions?
Read MoreStripping nickel from Inconel 718
Could you please advise me of the best way to strip sulfamate nickel off of Inconel 718 base material? Is there a risk of damaging the part if it is stripped in 50% nickel due to the high nickel content of the base material?
