How to make the surface treatment of titanium metric socket head cap screws harmless?

Australia’s Mark wants to order a batch of titanium metric socket head cap screws for use in bathroom equipment. I want to sample first when I first started.

Before placing the order, Mark said that the screw is not harmful to the human body, and that he wants black treatment. The solution should not contain nickel during electroplating. Later, Mark put forward some requirements for electroplating. Later, Shishitong recommended the customer to use the titanium metric socket head cap screws after the micro-arc.

But because the customer wants it is harmless. It can’t contain elements that are bad for the human body, and customers want black surface treatment. Micro-arc oxidation Because the harmful elements cannot be added, the treated color is light gray, the same color as the titanium wire.

The customer said that they should consider it. Later the customer said that it can accept the surface of the titanium metric socket head cap screws and the surface treatment of the micro-arc. After the customer received the screw sample, it was tested to see if he met his requirements. After the test, he said that he had met his requirements. And the requirement is to keep this quality unchanged during mass production. The current sample is very good.
