In high velocity oxy fuel (hvof) spray system, continuous combustion of the oxygen and fuel gas occurs in the combustion chamber and the resulting hot, high pressure gas is allowed to expand and accelerate through orifices into the nozzle. A carefully measured flow of powder is introduced axially into the nozzle, allowing sufficient heating and acceleration of the powder particles. The powder is heated and accelerated by the products of the combustion, usually to temperatures above its melting point and to velocities approaching supersonic velocities.

In detonation spray system, an explosive high temperature flux of gas mixtures (acetylene and oxygen) is used as a source for heating, accelerating and spraying the powder particles. The high temperature, high velocity gas products of the detonation melt the particles and accelerate them sufficiently so that they emerge from the gun at supersonic velocities depending upon the material being sprayed and its powder size characteristics. The resulting high velocity impingement of the particles on the substrate yields very dense coatings with excellent adhesion. This technology was developed and transferred by advanced research centre for powder metallurgy and new materials (arci), hyderabad.

Wide range of ceramic coatings are available to be applied on metals to enhance their properties needed for any specific function. Most ceramic coatings are electrically non-conductive and posses higher level of abrasion resistance and are able to maintain their property on higher temprature as well. Compatibility between ceramic material and metal is the most important aspect to be verified before applying ceramic coatings. Ceramic coatings are used mostly as barrier materials to incrase the interaction between moving parts widely useful for automobile industry. ceramic coatings are used under the temprature of 1200 degrees (F). If used with hot forging dies, then it increases the operational lifetime. There are many methods used for ceramic coatings, plasma spraying is also a type of ceramic coatings. Apart from these ceramic coatings method many more ceramic coatings methods has been found that may leave a major impact on ceramic coatings.

Tungsten Carbide Coatings is one of the most frequently used carbide coating process used in most wear and tear process. Tungsten carbide melts at 5200 degree forenheit, so most suitable. Coating properties such as hardness, wear resistance, and strength depend primarily on the grain size and volume fraction of the tungsten carbide particles, coating can be controlled based on the requirement in the process of carbide coating. Carbide coating is a very famous coating process and Tungsten carbide coating is the most loved carbide coating.

High velocity oxygen fuel (hvof) coating is a thermal spray coating process which helps to improve or restore a component's surface properties or dimensions. Hvof coating help to improve life of equipment by increasing resistance to any unwanted or tough conditions. In hvof coating semi molten or molten materials are sprayed on to the surface of material by high temprature, velocity to produce dense coating in this hvof coating method. Hvof coating is also one of the most sooth after coating in the industry. Benefits of hvof coating is reduced cost and high performance and these are the most attractive feature of hvof coating.

Abradable coating is made of abradable material, it means if it will be rubbed with any other abradable material, then the former will be worn. This abradable coating is mostly used in jets. Abradable coating solutions improve safety and reduce fuel consumption and emissions in turbomachinery. Whether for aviation gas turbines, or power generation gas or steam turbines, we have abradable materials for your clearance control applications. Abradable coating is highly used in turbines.

In the modern Industrial world, engineering components are prone to more rapid surface degradation due to mechanisms such as wear, oxidation, corrosion or failure under an excessive heat load. As a consequence, in an effort to achieve enhanced performance in terms of productivity, efficiency etc., surface modification technologies have been attracting a great deal of attention as they present a cost-effective way to combat degradation modes such as above without sacrificing the bulk properties of the component material. Thermal spraying is one of the most versatile coating technique and finds wide ranging applications in numerous industry sectors.
