Comparative study of wear mechanism of surface treated AISI 316L stainless steel

Abstract

Coating is a technique employed for the surface of materials to have thermal insulation, hot corrosion and oxidation resistance. Ion implantation forms modifications in surface composition or morphology of solids which yield to a change of physical and especially mechanical properties such as hardness and modulus of elasticity. The objective of this investigation is to concentrate on the friction and wear behaviour of TiN, N2 and Zr implanted and TiN and Tinalox PVD coated 316L stainless steel and compare with a substrate. Mainly stainless steels were of attraction, because they frequently demonstrate a poor tribological behaviour, which can be enhanced when they are hardened by incorporating N2, TiN Tinalox and Zr and forming a hardened surface zone.

The Influence of the Powder Characteristics on 316L Stainless Steel Coatings Sprayed by Cold Gas Spray

“…The corrosion potential (Ecorr) and corrosion current (Icorr) were calculated with the software EC-Lab V10.44. Ecorr was obtained from a Tafel Fit extrapolation, while Icorr was calculated according to the Stern-Geary Equation (2). Potentiodynamic polarization measurements were carried out, in accordance with the ASTM G59-97 [39] and ASTM G102-89 [40] standards, to determine corrosion resistance of the coatings in 3.5 wt.% NaCl water solution.…”

“…The operational and environmental conditions must be considered during their design, fabrication, maintenance and inspection steps, since wear or corrosion could occur in working conditions. For this reasons, the application of coatings on the new components have been widely used, employing different techniques, such painting, galvanizing, Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD), welding, thermal spraying, and other processes [1][2][3][4]. The selection of the protection methodology and coating materials depends on its purpose, such corrosion, wear, or cavitation resistance, or aesthetic purpose.…”

An investigation of different ceramic coating thermal properties

“…Latest works expose that microstructure and mechanical properties, such as grain size [12][13][14][15][16], porosity [17], hardness [18,19], fracture toughness [20], have strong effect on abrasive/sliding wear resistance of bulk ceramics and coatings under dry or lubrication circumstances. Among the reduction in the grain size of ceramics, their mechanical properties would be improved [21,22], which is helpful in improving the abrasive/sliding wear resistance of bulk ceramics and coatings [1,18,[12][13][14][15][16][17][18][19][23][24][25].…”

Slurry erosion performance study of HVFS sprayed Ni-20Al2O3 and Ni-15Al2O3-5TiO2 coatings under hydro accelerated conditions

“…Gupta et al (1995) proposed the following correlation for the prediction of erosion rate: where E W is designated for erosion rate, “V” velocity, “d” particle size, “C” is slurry concentration, whereas K, α , β and γ are designated for various constants whose magnitudes depend on the target material and erodent properties. Furthermore, considerable research studies have been conducted in the past to understand the mechanism of wear of uncoated and coated members (Dogan et al 2003 and Kiratli and Findik, 2011).…”
