Yttrium aluminium garnet (YAG) is a promising topcoat material for thermal barrier coatings due to its high temperature stability and better CMAS (calcium-magnesium-alumino-silicate) resistance. YAG topcoats were deposited by suspension solution precursor high-velocity oxy-fuel (HVOF) spray. The relationships between processing, microstructure final properties studied through range of character...

At present, cost-effective coatings that cause less pollution are in great demand; to decrease frictional losses, carbon-based hybrid composite have been developed using a high-velocity oxy-fuel (HVOF) spray process. The microstructural, tribological, corrosion, and mechanical properties of these evaluated high-resolution X-ray diffraction (HRXRD), field emission scanning electron microscopy-En...

Abstract WC-Co coatings sprayed by HVOF attracted much attentions, benefiting from the satisfactory wear resistance and high bonding strength to steel substrates. Nevertheless, density of conventional required excessive Co binder, which decreased hardness operation life. Based on this, a strengthened WC-30WB-10Co coating was developed with both improved hardness, using high-qualified thermal co...

Heat treatments were carried out at 350, 450, 550 and 650°C on WC-10Co4Cr coatings deposited by High-Velocity Oxy-Fuel (HVOF) onto AISI 420 stainless steel substrate in order to study their influence the abrasive wear resistance of coatings. The thickness microhardness measured while microstructure was analysed with aid OM, SEM XRD techniques. X-ray diffraction results revealed presence W2C pha...

Oxy-fuel combustion technology is an effective way to reduce CO2 emissions. An ionic liquid [emim][Tf2N] was used capture the in flue gas from oxy-fuel plant. The process of simulated using Aspen Plus. results show that when liquid–gas ratio 1.55, volume fraction exhaust controlled about 2%. When desorption pressure 0.01 MPa, efficiency 98.2%. Additionally, based on designability liquids, a hyp...
