摘要: Purpose: In this paper it was investigated the influence of laser treatment, first all power, to mechanical properties and structure steel surface layer alloyed with different ceramic powders. The purpose work also determine technological technical conditions for remelting HPDL. Design/methodology/approach: This presents discusses main methodology results new treatment techniques applied in metal technology are. There is presented hot tool 32CrMoV12-28 powders especially carbides, oxides nitrides as well on steel, carried out using high power diode (HPDL). Optical scanning electron microscopy used characterize microstructure intermetallic phases occurred. Findings: A coming into existence without cracks defects has a considerably higher hardness value compared non remelted material. increases according so that highest gives layer. Research limitations/implications: Four choused powers were alloying implicated by one process speed rate. which particle size range 5 10μm. Practical implications: helps use technique
