Dense ceramics are often measured for hardness by the knoop hardness test a method of microindentation optimized for brittle materials or thin coatings such as ceramic. Virtually each ceramic coating can attain 9h within the pencil hardness scale. 9 layers for experimental test purposes only.

Its basis is the pencil scale of hardness used by most graphic designers professional artists and many others to pick a pencil lead strength. The knoop hardness test is most practical for the purpose of ceramic coating tests as only a small indentation is required to evaluate and measure a material s hardness. The coating would have to be reasonably thick over 150 microns and it should be relatively slippery surface slip is an easy way to fool the pencil hardness test as it doesn t give the pencil the opportunity to bite. What is a ceramic coating.

It s based on the pencil scale of hardness which is used by professional artists graphic designers and more to pick a pencil lead strength that helps them with writing or drawing projects. Another common test of hardness for coatings is the infamous pencil hardness test or the wolff wilborn test. 9h refers to the level of hardness test of the ceramic coating once it cures on the surface. 9h is a test for the hardness level of the ceramic coating once the surface is cured.
