Aerofin Laboratories can determine the hardness of a material. Hardness is evaluated using a microhardness tester to indent the coating, creating an impression which can be measured.
Microhardness is frequently used to assess the hardness of coatings and to assess their suitability for function in service e.g. chrome, nickel and hard anodise where impact and wear resistance (rotational and recpricol) are important.
Aerofin can also measure Shore Hardness if you require.
