In-Situ Heating Effect Of Laminar Plasma Jet During Mo Coatings Deposition

Laminar plasma has the characteristics of a long plasma jet, low velocity, and high temperature, which make it able to cover and heat the substrate during the spraying process. The results show that when the standoff distance is short, the coating is strengthened by in-situ heating of the plasma jet and shows higher erosion resistance at high erosion angles and bulk-like material tendency. When the standoff distance is long, the substrate temperature is low, the coating shows higher erosion resistance at a lower erosion angle.
