Micro-Scale Abrasive Wear Testing of CrN Duplex PVD Coating on Pre-Nitrided Tool Steel

Characterization of CrN/TiN PVD Coatings on 316L Stainless Steel

In order to further enhance tribological properties 316 Low carbon stainless steel (L SS) used on mechanical parts. CrN/TiN with DC magnetron sputtering sources was carried out on PVD 316 L SS. The micro structure of the CrN/TiN coatings were investigated by Scanning electron microscope (SEM), X-ray Diffraction (XRD) and tribology properties were investigated on a Pin on Disc friction and wear ...

Wear Performance of Ti Based Powders Coating on SS 304 by PVD Method

The PVD techniques range over a wide variety of applications from decorative, to high temperature superconducting films. The thickness of the deposits can vary from angstroms to millimeters. A very large number of inorganic materials—metals, alloys, compounds, and mixtures—as well as some organic materials can be deposited using Physical vapour Deposition (PVD) technologies. Traditionally, the ...

Improving the Wear Resistance of Moulds for the Injection of Glass Fibre–Reinforced Plastics Using PVD Coatings: A Comparative Study

It is well known that injection of glass fibre–reinforced plastics (GFRP) causes abrasive wear in moulds’ cavities and runners. Physical vapour deposition (PVD) coatings are intensively used to improve the wear resistance of different tools, also being one of the most promising ways to increase the moulds’ lifespan, mainly when used with plastics strongly reinforced with glass fibres. This work...

Effect of Abrasive Size on Wear

Tribological and Wear Performance of Nanocomposite PVD Hard Coatings Deposited on Aluminum Die Casting Tool

In the aluminum die casting process, erosion, corrosion, soldering, and die sticking have a significant influence on tool life and product quality. A number of coatings such as TiN, CrN, and (Cr,Al)N deposited by physical vapor deposition (PVD) have been employed to act as protective coatings due to their high hardness and chemical stability. In this study, the wear performance of two nanocompo...
