Abstract
The invention relates to a process for coating or hardfacing recharging a part by means of a plasma transferred arc. According to the process, on the part (1) to be coated or hardface is deposited at least one weld bead (7a, 7b, 7c) of said material solely by means of the plasma transferred arc (5), by moving the plasma relative to the part at a speed of 1.5 to 50 m/min and using a power of the plasma such that the surface of the part is melted over a thickness at the most equal to 0.5 mm and so that the enlargement of the grains in the melted area does not exceed 10%, without cooling the part during recharging.
