ABSTRACTTiN films are prepared by reactive rf magnetron sputtering on carbon steel substrates which are widely applied as structural materials. The electroless Ni-P plating is introduced as an interlayer in the surface modification of TiN coating. The electroless Ni-P deposit crystallizes during rf sputtering due to the elevated sputtering temperature and thus a TiN/Ni3P/Fe coating assembly is formed.The employment of electroless Ni-P deposit results in an increase in the surface microhardness and adhesion strength. The surface hardness as high as 2266HK1 close to the hardness of bulk TiN can be achieved in the Ni3P interlayer modified TiN coating. With respect to the wear-resistance, the adhesion of the TiN coating plays an important role for the sliding wear-resistance and the interlayer Ni3P acts as a hard , barrier instead of the soft carbon steel substrate.

The mechanical properties of TiAlN deposited on the steel are explained in this study. Thin films are deposited by RF magnetron sputtering on the steel substrates to improve the wear resistance and hardness of the samples. Due to their improved microstructure and nanograins, the nanofilms have improved the mechanical properties of the steel substrate surface. The thin film deposited has improved the wear resistance by 80% and has improved the hardness by 95%. The deposited thin films are tested for hardness by nanoindentation and wear test by the pin-on-disk test. SEM has tested films for their microstructure and adhesion by nanoscratch test.

The tribological properties such as surface hardness, friction and wear have been studied for AISI 316L stainless steel substrates which were co‐ion implanted with zirconium and oxygen ions. It is found that the wear resistance for AISI 316L stainless steel substrates implanted with zirconium and oxygen ions increased quite a lot. It is concluded that the increase in surface microhardness and the decrease in friction coefficient of AISI 316L stainless steel substrates play an important role in improving the wear resistance, and the relationship between relative wear volume and microhardness is correlated for zirconium and oxygen co‐ion implantation.

Electroless Ni-P coating containing ZrO2particles was successfully co-deposited on low carbon steel substrate. The surface and cross-sectional micrographs of the composite coatings were observed with scanning electron microscopy (SEM). And the chemical composition of the coating was analyzed with energy dispersive spectroscopy (EDS). The oxidation resistance was evaluated by weight gains during high temperature oxidation test. The results showed that the embedded ZrO2particles with irregular shape uniformly distributed in the entire Ni-P matrix, and the coating showed a good adhesion to the substrate. The weight gain curves of Ni-P-ZrO2composite coatings and Ni-P coating at 923K oxidation experiments were in accordance with . The ZrO2particles in Ni-P matrix could significantly enhance the high temperature oxidation resistance of the carbon steel substrate as compared to pure Ni-P coating.

through super-hard wear-resistant surface electrode surfacing D707 in Low-carbon steel. We have analysis the effect of welding process parameters and post-weld heat treatment process on low carbon steel surface hardness of cladding layer. The experimental results show that: after quenching hardness value no significant change; But after annealing the hardness value decreased and after annealing the crystal grain of the underlying tissues uniformization become tiny. micro-hardness testing is carried out in the weld cross-section, we have find out that from the base metal to the cladding layer the surface hardness values is getting higher and higher, while the indentation is getting smaller and smaller. Because hardness is a measure of wear resistance materials, thus it can indirectly show that when low-carbon steel surface electrode in the super-hard wear-resistant surfacing welding layer, it can improve the surface hardness of low carbon steel and improve wear resistance of low carbon steel surface.

Tin Coating

Titanium nitride (TiN) coating has been used in various application as it gives excellent performance in many aspects. It has been proven to prolong machining tool life since the mid-1960s. Industrial deposition processes of TiN, including magnetron sputtering, arc ion plating, and chemical vapor depositions, have their individual advantages and limitations. Due to the rising demands of the dry machining technique, the massive amount of heat generated from the friction of cutting tools against the surface of a work piece has become the main issue to overcome. Oxidation of TiN, which occurs around 400 °C, puts a limit on the applications of the coatings. Comparing TiN tool coatings deposited by arc evaporation, the novel high-power impulse magnetron sputtering (HiPIMS) technology provides smoother film surface, denser structure and subsequent corrosion resistance. Therefore, this research aims to investigate the wear behavior of TiN thin film deposited by HiPIMS at high temperature. The influences of the coating properties on the wear resistance of coatings at high temperature are also investigated. The results show that the HiPIMS technique enables a denser epitaxial-grown TiN coating with higher surface hardness and adhesion in contrast with TiN coating deposited using direct current (DC) magnetron sputtering techniques, which provides a higher wear resistance.

Abstract FeMnCrSi and 316L alloy coatings were deposited on carbon steel substrates via high-pressure cold gas spraying and their microstructure, hardness, and wear resistance were obtained. Ball-on-disk testing (ASTM G99) was used to measure sliding wear behaviors. The mechanism of wear was found to be the same for both coatings, although FeMnCrSi had a higher coefficient of friction while 316L had less volume loss.

ABSTRACTThe results obtained upon reactively RF sputtering indium - tin oxide (ITO) films are presented. It is found that while the amount of oxygen in the chamber is very critical in determining the properties of the films, it is easy to deposit reproducible films even at low oxygen concentrations when using an oxide target. At concentrations of oxygen below 2 vol% the films deposited exhibit almost metallic conductivities, while retaining an average transparency in the visible range of over 85%. The resistivity of these films increases with the oxygen concentration in the chamber, but the transition is not as sharp as that observed upon sputtering a metal target. These films are found to have very good “figures of merit” and are promising in their use as transparent conductors.

Plasma Surface Alloying

High quality TiN/Ti multi-layers have been successfully obtained on a carbon steel substrate by double glow plasma surface alloying technique (DGP). The TiN/Ti multi-layers consists of deposition layer and diffusion layer, and then on its surface TiN film (PVD) is deposited to form TiN/TiN/Ti compound multi-layers. In addition, studies were carried to compare TiN/Ti multi-layers, TiN/TiN/Ti compound multi-layers and TiN film (PVD) directly deposited on the surface of the carbon steel and their microhardness and dry friction-abrasion properties were also investigated. The results show that the thickness of TiN/Ti multi-permeated layers is above 10*m; Ti and N concentrations change gradually along the depth of alloying layer. TiN/Ti multi-layers and substrates are metallurgically bonded. Preferred orientation of TiN/Ti multi-layers is crystal surface (200). The hardness of the TiN/Ti multi-permeated layers ranges up 2200HV, its average friction coefficient is lower, abrasion crack is shallower and wear resistance better.
