Indentation testing of thin titanium coatings sprayed with cold gas

Material hardness is one of the basic parameters characterizing the properties of matter. In the nanohardness studies, the intendant’s deformation can not be ne glected. Assuming the proportionality of the intender’s deformation to the hardness of the material being tested, a relative hardness measurement was used in the work. Hardness measurement was carried out for fused silica, which was a reference sam ple. With the same nanotesting parameters, a nanoscale measurement was carried out for two samples.
