COATING ALLOY OBTAINED BY POWDER SPRAYING

摘要

The invention relates to a method for coating a metal substrate by deposition of a metal powder, characterised in that said metal powder includes a zinc, aluminium and magnesium mixture or alloy with 0.1 to 15 wt % of aluminium, 0.1 to 50 wt % of magnesium and optionally 0.2 wt % at most of silicon, and in that, during the deposition, the substrate is heated to a temperature higher than the lowest temperature at the liquid state of the chemical elements and alloys thereof that form the powder, so that said powder can melt at least partially when in contact with the substrate.
