nickel crushing process
An Ultimate Guide to Plating on Titanium
The process, in general, contains the following steps: Use a solvent to reduce the grease on the substrate. Use pumice powder paste to scrub the surface in water. Clean the substrate thoroughly with an alkaline cleaner. Rinse the substrate by submerging it into a solution of 500ml of HCL with 500ml of water.
