Stainless steel reinforcing has an elevated chloride threshold and is an attractive alternative for prestressed concrete applications. However, due to the high strength requirements for prestressing strands, concern exists about the possibility of stress corrosion cracking (SCC). This investigation screened for potential SCC development three candidate high strength alloys for use as prestresse...

For a large number of non-oxide ceramic/metal as well as for non-oxide particulate reinforced composite/metal tribocouples, oxidative wear is reported to play a major role in the overall damage and material removal process. The designing of new materials with improved resistance to oxidative wear requires understanding of the combined effect of the material properties and operating parameters o...

The study aims to investigate the influence of environmental media on friction and wear behavior low-alloy wear-resistant steels provide practical references for their application. This article conducted sliding tests NM500 steel under different loads air atmosphere, deionized water, 3.5 wt% NaCl solution conditions. Someone quantitatively measured coefficient amount each pair. present employed...

Abstract This study explores the use of powder plasma transferred arc welding (PPTAW) as a surface layer deposition technology to form hardfaced coatings improve upon wear resistance mild steel. Hardfaced layers were prepared using PPTAW process with two different wear-resistant powders: PG 6503 (NiSiB + 60% WC) and PE 8214 (NiCrSiB 45% WC). By varying parameters gas flow rate (PGFR) current, p...

*Member of ASM International arburizing has been a popular method for obtaining a unique balance of properties in steels for many years. Steels with low carbon contents are characterized by good toughness and good ductility, but low strength and low wear resistance. By locally increasing the carbon content at the surface, followed by heat treatment to produce a very high hardness in this layer ...

The work is devoted to the problem of an increase in proportion scrap metal castings smelted and produced from wear-resistant chromium cast irons. Castings obtained with more than 60% armor cracked during solidification subsequent heat treatment were selected as research objects. similar mill after operation characterized different wear resistance compare characteristics structure properties. c...
