"tin Coatings for Wear Resistance and Gold-like Decorative Coatings"

Titanium Nitride (TiN) coatings have led the way for providing increased wear resistance and extended life of cutting tools, whether carbide inserts or high-speed steel. Where the earliest applications were for high temperature substrate materials (carbides) and chemical vapor deposition (CVD) was the process of choice, later developments in the physical vapor deposition (PVD) technology, espec...

Thermal Spray Coatings

THERMAL SPRAY is a generic term for a group of processes in which metallic, ceramic, cermet, and some polymeric materials in the form of powder, wire, or rod are fed to a torch or gun with which they are heated to near or somewhat above their melting point. The resulting molten or nearly molten droplets of material are accelerated in a gas stream and projected against the surface to be coated (...

Numerical (CFD) Analysis of Thermal Spray Coating Process

Active Infrared Thermography for Non Destructive Evaluation of Defects in Wear Resistance and Thermal Barrier Coatings

In fossil fuel power generation plants, steam generation tubes and turbine blades are critical for overall performance of plant. The materials are subjected to bear heavy wear and temperature during operation. The manufacturer has an option of using high wear resistant and high temperature materials which are costlier or using cheaper materials with ceramic coatings over it. The coatings expose...

Improving the surface wear resistance of aluminum by electrical discharge process

In this study electrical discharge process was used to increase surface wear resistance of pure aluminum. Pulse-on-time and pulse current were considered as input parameters of the electrical discharge process. Experimental results reveal that the electrical discharge process is a successful method for improving the surface wear resistance of aluminum, so that this method has greatly increased ...
