Hardening of Ni-W coating by laser treatment

Hardening of Ni-W coating by laser treatment

Calorimetric studies showed that the electrodeposited nanocrystalline coating Ni-37 wt % W does not undergo phase transformations to a temperature of 1000 °C. The effect of laser treatment was studied and it was shown that in the selected mode it leads to significant grain growth in the coating, but...

Zusammenfassung:Calorimetric studies showed that the electrodeposited nanocrystalline coating Ni-37 wt % W does not undergo phase transformations to a temperature of 1000 °C. The effect of laser treatment was studied and it was shown that in the selected mode it leads to significant grain growth in the coating, but does not affect the chemical composition. A significant increase in microhardness of the coating was revealed with a certain amount of energy.
