Study of Adhesion in Steels Surface Hardened
Abstract:
This study evaluates the adhesion of boride layers on the surface steels of AISI 4140, 8620, W2 and H13 by standard VDI 3198 [1], the surface hardened was carry out by the technique of power pack boriding at the temperatures of 1273 K, with time exposition of 6 and 8 h. The presence of boride phases was determinate by X-ray diffraction (XRD) analysis. A Rockwell C indentation tester was applied on the surface steels boriding, this impact test determines qualitatively the adhesion on layer/substrate indentation print and Vicker microhardnes was evaluate a load of 2.9 N on phase FeB and Fe2B, the steels have scale delamination H1 to H6.
