Реферат: Detonation spraying is used for the binary fuel spraying, C2H2/C3H8/O2 of WC/Co and Cr3C2/NiCr powder. The particles-in-flight temperature and velocity are calculated and optimized. Spraying distance is varied from 50 to 400 mm and substrate inclination relatively spraying direction is varied up to 60°. Coating properties: microstructure, microhardness, porosity, wear resistance are measured and it is found that binary fuel detonation spraying provides high coating quality. For example, for the WC/Co (88/12 wt%) coatings: porosity is less than 0.7%; microhardness is about 1500 HV300; ASTM G65 abrasion wear is 1.17 mm3/1000 rev when using a corundum powder as an abradant. For the Cr3C2/NiCr (75/25 wt%) coatings porosity is less than 1.7%, microhardness is about 800 HV300, and abrasion wear is 2.7 mm3/1000 rev. It is found that the coating performance does not decrease strongly with the substrate inclination up to 30°. The industrial applications include machinery, aircraft, petrol, gas turbines domains, etc.
