Abstract
Abstract Once with the technological development, many variants of improving surface behavior through coating with various materials have emerged. In this paper are studied the microstructure, adhesion to the substrate and the utilization properties of thermal plasma coatings on alloy steel substrate (100Cr6). The samples were obtained by plasma spray from three types of powder, both with the bonding and non-bonding versions: Sample 1 - topcoat of Eutalloy 10112 (Ni-Cr-B-Si-Fe-WC), Sample 2 - bonding layer from NiAlSi and Eutalloy 10112 as topcoat; Sample 3 - NiCrFe topcoat (M42); Sample 4 - bonding layer of NiAlSi and NiCrFe topcoat (M42). The samples were analyzed for microstructural changes both longitudinal and in the cross section (for evaluation of the modifications produced at the substrate - coating interface). The adhesion to the substrate was evaluated by the scratch method, applied both longitudinally and in the cross section of the coatings. The results revealed that all the coatings have a good adherence at the substrate and are suitable for applications where wear resistance is needed
