Tool life and wear behavior were investigated in an AISI 01 carbon tool steel, surface alloyed with tungsten using a CO2 laser. Results show improved hardness in the steel due to the formation of microstructure phases Fe3W3C and W2C. Machining performance of the alloyed steel was enhanced because of the wear resistance properties. Tool life was 23 times greater than that of the uncoated steel. Tool wear of the alloyed ...
