Abstract (en)
Coating method comprises thermal spraying simultaneously with 92 - 95 wt% of an iron alloy and 0.5 - 8 wt% of boron carbide. The alloy contains 5 - 25 wt% of chromium and 0.5 - 5 wt5 of molybdenum. Independent claims are included for: (A) coatings produced using the method; (B) the coatings when applied to the contact surfaces of cylinders in light metal engine blocks; (C) and apparatus for carrying out the method comprising a spray head (2) with a feed system for two iron alloy wires (4, 5) which allow an arc to be formed, a nozzle (11), through which gas (12, 13) is fed and a feed (14) for boron carbide powder.
