I want to measure the microhardness of the alumina but the imprint not visible under the maximum load (1kgf) .Should I use a durometer to measure it ?

21 June 2022 0 321 Report

I have two samples welded together (Aluminum with alumina ) how can i measure the microhardness of the two parts using the same machine ? if it is impossible i must use durometer to measure the hardness of the two samples ?
