Abstract
ABSTRACTAt present, the industrial sector requires the recovery of tool steel components subjected to severe wear which are built with steel HWS these have the same properties in all tribology directions and have great success in building tooling. In this paper, we recover the previously HWS steel machining with a fillet of 2mm caused by the metallurgical recovery of the component, applying the process of plasma transferred arc PTA which has very good fats dilution properties in comparison to other conventional processes currently applied for the recovery of tooling, such as GTAW, SMAW, SAW. The experiment was conducted with input D2 and M2 with one and two welding seams, making the assessment metallography, hardness and wear tests pin-on-disk. Finding a decrease in the hardness of the interface line, according to the evaluation of wear pin-on-disk, had a higher wear rate of the filler metal in the M2 D2.
