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...
امروزه کاربرد پوشش های سرمت به روش پاشش حرارتی با سوخت اکسیژن در سرعت بالا، hvof، در صنایع مختلف، بسیار مورد توجه است. زبری سطح پوشش های کاربیدی پس از فرآیند پاشش حرارتی، بالاتر از مقادیر قابل قبول در شرایط کاربردی است، بنابراین به منظور دستیابی به زبری سطح مطلوب، سطح پوشش توسط فرآیند سنگ زنی پرداخت می شود. در این مقاله، تأثیر تغییرات همزمان سه پارامتر اصلی فرآیند سنگ زنی شامل سرعت برش، نرخ پیش...
Increasing the hardness and wear resistance of powder alloys coatings through use ultrafine-grained powders metastable phases is a promising way in metallurgy. This paper presents results studies process obtaining ultrafine by electric discharge erosion cemented carbide waste WC-5TiC-10Co on special installation. An empirical model that describes dependence productivity energy properties liquid...
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...
High-entropy alloys (HEAs) hold promise for achieving excellence performance due to unconventional composition and structure. In this paper, the effect of FeCoCrNiAl HEAs as binder instead Co on microstructure WC cemented carbide was investigated. The isothermal oxidation resistance WC-HEAs carbides with 6, 10, 15 % studies at 700, 800, 900 1000 °C. results revealed that microstrcture dense, av...
The tensile properties, 7-E transformation and shape recovery have been related to the orientation of tensile axes i.e., along rolling direction(specimen 'A') and toward 45" to the rolling direction(specimen 'B') in a cold-rolled and then annealed Fe-1SMn -10Co-SCr-3Si alloy. It is revealed that the deformation modes of the specimens 'A' and 'B' with respect to tensile axes are not the same; te...
