Is The Coating Wear-Resistant Enough

       

The customer said that the hardness of the
coating was not wear-resistant. What should I do？

Wococarbide provides powders of various
hardness. When customers buy powder according to their own needs, but the
feedback says: the quality of the products I buy from you is not good, and the
coating is not wear-resistant. Similarly, we should first understand how
customers test.

A customer used an angle grinder to grind
our thermally sprayed coating, and then told me: "the coating you made is
not wear-resistant, I can grind it off with an angle grinder.

Later, I gave this client an "example
of water dripping on a stone". I believe everyone can understand this
simple fact. In this world, nothing will not wear out, because it is not enough
to complete the work. Another problem is that the oxide layer on the surface of
the coating is polished off to reveal the metal color, which does not mean that
the coating has disappeared. The tungsten carbide coating will brighten after
polishing. When many customers use it, the coating is smooth, and it is said
that the coating has disappeared. This analysis is very arbitrary. The main
method is to use spectrometer to analyze whether the coating still exists.

Remember that we must use scientific
methods to judge the hardness, wear resistance and corrosion resistance of the
coating, so as to make it reasonable and based, rather than using some methods
that violate the regulations.
