Fatigue Bending of V-Notched Cold-Sprayed FeCoCrNiMn Coatings

Solid Particle Erosion of Thermal Sprayed Coatings

Solid particle erosion is an important material degradation mechanism. Although various methods of coating are tried and used for protection against erosion, thermal sprayed coating for such purpose is the most widely used method. In this chapter, evolution of thermal sprayed coating, erosion testing methods, and erosive wear of thermal sprayed coatings are discussed extensively with emphasis o...

Study of Wear Behaviour of Hvof and Cold Sprayed Coatings on Boiler Steels

In this study two commonly used steels in boiler plants, i.e. (SAE-213) T-22 and SA516 (Grade-70) were coated with different thermal spray processes namely HVOF and cold spray. The coating powder used was made up of NiCrTiCRe powder. The performance of the coated as well as uncoated material was investigated using a pin-on-disc machine [Model: Wear and Friction Monitor Tester TR-20], supplied b...

In Vitro Immersion Behavior of Cold Sprayed Hydroxyapatite/Titanium Composite Coatings

In previous study, dense and homogenous 20wt% HAP/Ti composite coatings were successfully deposited on Ti substrates by cold gas dynamic spray technique. The results revealed that the phase composition of the HAP in the deposit is identical to that of the precursor powder and the bonding strength of the deposit is comparable/better to that of the plasma sprayed HAP. A relatively higher corrosio...

A Review on Detonation Gun Sprayed Coatings

Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is one of the thermal spraying techniques known for providing hard, wear resistant ...
