Martensitic steels have been successfully employed in resource-based industries where components must endure aggressive conditions. In industrial practice, many parts of these are joined by welding techniques. The aim this work was to understand the influence on wear resistance quenched and tempered carbon martensitic steel subjected dry linear reciprocating sliding micro-wear tests. Weld-joint...

The paper presents the results of research that is focused on renovation molds for high-pressure aluminum casting. An analysis worn was carried out after they were removed from operator. extent and mechanism wear determined. GTAW (Gas tungsten arc welding) technology chosen shaped parts molds. layers realized with four types additional materials Cronitex RC 44, UTP A 73 G 3, 673 Dievar® TIG. qu...
