摘要

Wire-like spray material (4) comprises iron, where: the spray material is formed together with carbon as a micro-alloy, so that bainite and martensite are developed during hardening of the spray material, and the alloy contains carbon (0.23-0.4 wt.%); silicon (0.7-0.98 wt.%); manganese (1.4-1.9 wt.%); chromium (0.75-0.95 wt.%); copper (0.2-0.25 wt.%); molybdenum (0.07-0.095); nickel (0.15-0.25 wt.%); aluminum (greater than 0.05 wt.%); vanadium (0.17-0.2 wt.%); nitrogen (0.005-0.013 wt.%); boron (0.0015-0.0025); and titanium (0.02-0.035 wt.%).
