چکیده
Abstract A high-vanadium alloy composite layer was prepared on the surface of a carbon steel using cast technology, and wear properties were investigated. The results showed that microstructure composed primary vanadium carbides (VC), flake martensite, residual austenite, fine VC. hardness 63 HRC. abrasive resistance impact increased by 60% 26%, respectively, compared with those high-chromium iron. excellent is attributed to high-hardness carbide large number secondary precipitated out layer.

متن کاملElectrocatalytic properties of platinum and it's binary alloy with vanadium in oxygen reduction reaction(ORR)
The electrocatalysis of the oxygen reduction reaction (ORR) on carbon supportedPt-V (1:1) catalyst in polymer electrolyte fuel cells (PEFC) was investigated. Atan oxygen pressure of one atm an enhanced electrocatalytic property of Pt-V/Ccompared with Pt/C is revealed. These results indicate the occurrence of adifferent electrocatalytic mechanism for the ORR on Pt/C and Pt-V/C. Anincrease of mas...
متن کاملIn vitro human monocyte response to wear particles of titanium alloy containing vanadium or niobium.
Our aim was to determine whether in vitro studies would detect differences in the cellular response to wear particles of two titanium alloys commonly used in the manufacture of joint replacement prostheses. Particles were of the order of 1 microm in diameter representative of those found adjacent to failed prostheses. Exposure of human monocytes to titanium 6-aluminium 4- vanadium (TiAlV) at co...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

The aim of this study is to reach an increased service life for parts using in sour environment by weld overlaying process. In this investigation, two successive layers of ER410NiMo were clad on low alloy steel substrates. To reduce the likelihood of Hydrogen Induced Cracking (HIC) and producing stable hydrogen traps, Post Weld Heat Treatment (PWHT) was conducted. Microstructural analysis, X-ra...
