Effect of Grinding Parameters on the Fracture Toughness of WC–10Co–4Cr Coating Deposited by HVOF
Nowadays, application of cermet coatings deposited by High-Velocity Oxygen-Fuel (HVOF) has received considerable attention in a variety of industries. Carbide coatings have high surface roughness, so it is essential to grind the coated surface. The present investigation studied the effect of simultaneous changes in the grinding parameters including the depth of cut, feed rate and cutting sp...
متن کاملModeling and control of HVOF thermal spray processing of WC–Co coatings
This work focuses on the modeling and feedback control of the high velocity oxygen fuel (HVOF) thermal spray processing of WC–Co coatings. A first-principles-based process model is proposed to explore the fluid dynamics and particle inflight behavior in the HVOF flow field. Rule-based stochastic simulation, which encapsulates the main features involved in the deposition process, is used to capt...

متن کاملTribological Properties of B4C-Ni Cermet Coating Produced by HVOF Process on the Surface of 4130 Steel
In this research, B4C-Ni cermet coating was sprayed on the surface of 4130 steel from B4C and Ni feed-stockpowders using high velocity oxy-fuel (HVOF) method. In order to characterize the tribological behavior of thecoating, ball on disk wear tests were done at the ambient temperature and under the loads of 1, 3 and 5 N.Phase analysis of the coating after spraying was studied ...
متن کاملSynergistic effect of ultrasonic cavitation erosion and corrosion of WC-CoCr and FeCrSiBMn coatings prepared by HVOF spraying.
The high-velocity oxygen-fuel (HVOF) spraying process was used to fabricate conventional WC-10Co-4Cr coatings and FeCrSiBMn amorphous/nanocrystalline coatings. The synergistic effect of cavitation erosion and corrosion of both coatings was investigated. The results showed that the WC-10Co-4Cr coating had better cavitation erosion-corrosion resistance than the FeCrSiBMn coating in 3.5 wt.% NaCl ...
