Aerospace Special Process / Chemical Cleaning & Blue Etch
 
1. Chemical Cleaning
Chemical cleaning technology uses chemical methods to remove the dirt on the surface of the object and restore the surface state of the object, so that the subsequent process can be executed without any dirt. This technology has been certified by the original customers, Safran group, GE Aviation, and NADCAP.

2. Metal Pickling
Metal pickling is a pre-passivation technology that uses hydrofluoric acid solution to treat stainless steel parts. It can eliminate oxide scale and dissolve the metal that penetrates into the product surface, leaving the surface fully alloyed stainless steel surface. CHPC develops metal pickling technology to remove surface oxides produced by high temperature processes such as welding and heat treatment of various products, and improve the corrosion resistance of the product surface. This technology has been certified by Safran group.

3. Titanium alloy Blue Etching
Titanium alloy Blue Etching as one of aerospace expertise technology, mainly use on titanium 64 alloy (component Ti-6Al-4V) for electrochemical discolor reaction. By observing the trend of discoloration, it will able to determine if any defecting during material manufacturing process, such as uneven forging cooling and mechanical processing burn. In order to create an outstanding Blue Etching contrast, related processing parameters and rectifier control are very strict. This technology has been certified by our customers Safran group, GE Aviation and NADCAP.
