Failure and wear of tools made of high speed steel (HSS) is a common cause of production slowdowns or interruptions. Renovation of structures made of high-speed tool steel can significantly reduce production costs and time needed for resumption of production. The Tool steel of HSS 23 type (M3/2, PMHS6-5-3C) was cladded on substrate of the same type of steel and heat-treated. The influence of hardfacing parameters on both macro- and microstructures was studied by light and electron microscopy. Development of hardness from substrate to deposit was measured by Vickers method. Metallurgical bond between parent material and deposit was created. The deposits are free of cracksKeywords: Pulsed PTA, PTA hardfacing, High Speed Steel, Microhardness, renovation
