Effect of Deposition Regime on Tribological Behavior of VK8Coating on 1.2344 Tool Steel Obtained by Electro Spark Method
In this study, the effect of deposition regime on the wear behavior of VK8 coating applied to 1.2344 tool steel by electro spark method (ESA) was investigated. After sample preparation, the coating with high and low regime was applied. To assess the wear behavior, the pin on disk test method according to ASTM G99-04, was used. For surveying surface morphology and cross section of the coating as...
متن کاملEffect of Gas Ratio on Tribological and Corrosion Properties of Ion Beam Sputter Deposited TiN Coatings
Titanium nitride thin films were grown on 304 stainless steel substrates at various nitrogen/argon flow ratios by ion beam sputtering (IBS) technique. The current research is a follow up study on the influence of gas ratio on structural and corrosion properties in the TiN coated 304 stainless steel. Film structural identification of phases was performed using X-ray diffractometry (XRD). Sca...
متن کاملEvaluation of tribological properties of (Ti,Al)CN/DLC composite coatings deposited by cathodic arc method.
In this study, Ti, Al and N doped DLC – referred to here after as “(Ti,Al)CN/DLC composite”- coating and pure diamond-like coating (DLC) were produced by cathodic arc deposition technique and the effects of the coating thickness on their tribological properties were evaluated. The coatings were characterized, using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffrac...

15 صفحه اولAntibacterial and Tribological Performance of Carbonitride Coatings Doped with W, Ti, Zr, or Cr Deposited on AISI 316L Stainless Steel
Carbonitride (CNx) coatings have existed for several decades but are not well understood. Related studies have indicated that CNx coatings exhibit behaviors comparable to diamond-like carbon (DLC) coatings. Metal-doped CNx coatings are expected to show superior performance to single CNx coatings. In this study, a CNx coating and a group of CNx coatings with 6 at. % metal doping (W, Ti, Zr, or C...
