I have performed the scratch test on coated ss316l substrate. I got some data in numbers in word file but parameters are not mentioned there.

Initially, a graphical representation should be generated, illustrating the relationship between the friction coefficient during scratching and the elapsed time (SFC vs Time). Next, the calculation and examination of the volume affected by the scratching process are necessary. Lastly, the analysis of the scratched surface's profile should be conducted, employing SEM and 3D optical profilometer images to investigate its topographical characteristics.

Amari Djamel

the scratch test is based on the determination of penetration loads during the test. then we must see the relationship between the advancement of the indenter during scratching and the load used, namely the determination of Lc1, Lc2, Lc3,... each load causes deformation of the coating. and as a result the coating undergoes delamination, flaking, etc. For your information, we can even determine the Young's modulus by the scratch test, because the indenter advances and compresses the covering in front of it and the covering behind the indenter undergoes traction.
