The Influence of Hardening Related Deformations on Selection of Abrasion Inhibition Process
Wear mass loss on samples was compared at depth of hardened layers of induction quenched C 60, carburized 16MnCr5, hard faced with C-Cr-Mn and C-Cr-W-Co electrode deposited layers as well as thermal flame sprayed deposits of C-Cr-Mo layer. Measurements of surface hardness, changes of sample surface hardness towards the core and metallographic examination of the structure were carried out using SMT 1-2070 wear and tear testing device, consisting of a disc and a bracket, in a chamber filled with oil containing SiO2. Wear mass loss on samples in the shape of disc in depth of the hardened layer was measured. Counter body in the form of pedal was made out of material GG 20. It was established that wear mass loss changed the least with the hard faced C-Cr-W-Co layer, after that with thermal flame sprayed deposits and hard faced C-Cr-Mn layers. Then some surface hardened and at last cemented layers, which displayed greatest wear mass loss. Correspondingly, conclusion was drawn that there was need for additional caution when selecting an adequate wear protection process for those machine parts that, due to macro deformation, require surface abrasion as final machining operation.
