Question

The coating of ceramic particles over metallic substrates with
better adherence may be produced by​

Answer 1

Answer:

The group of coatings more noble than the substrate includes such metals as chromium, nickel, and copper. The protection afforded by such coatings depends entirely on their continuity, since at holes in such coatings enhanced corrosion of the base metal usually occurs. These coatings are used in many applications in spite of the risks involved because they impart special properties such as luster, hardness, and electrical conductivity.
