| Abstract: | The amorphous FeSiBP coating was fabricated on 304 stainless steel matrix by high velocity oxygen
fuel (HVOF). The microstructure, friction properties and wear mechanism of the coating were analyzed by
scanning electron microscopy, X-ray diffractometer, Vickers microhardness tester, friction and wear tester, threedimensional optical profilometer and other equipments. Results showed that most of the coatings were amorphous,
and the amorphous content increased first and then decreased with the increase of heat input. When the spraying
parameters were kerosene flow rate 5.5 GPH, oxygen flow rate 2000 SCFH, powder feeding rate 4 RPM, spraying
distance 360 mm. The coating amorphous content can reach 83.8%, and the hardness was 857 HV0.2, wear
resistance was 2.52 times of the 304 stainless steel matrix. |
