Hard coatings have been successfully used for protection of materials and particularly to enhance the life of cutting tools since the 1970's and it is defined by its hardness which is the measure of resistance to plastic ...

The present investigation forms a part of a series of invest igat ions - that have been izad:rtak.on in this ea-artmentt on a study of aluminium and its alloys. The various physical and mechanical properties studied ...

A comprehensive review of the literature revealed that abrasion resistant white irons can be classified as (i) plain carbon and (ii) alloyed. The plain carbon white irons comprise of a microstructure consisting of pearlite ...

In many engineering systems like gas turbines, steam generators etc. materials come in direct contact with corrosive condensed phases which cause hot corrosion. The sources of these phases are the fuel and air necessary ...

Hot corrosion is an acute form of corrosion occurring at elevated temperature in the presence of an oxidizing gas and is associated with a thin electrolytic deposit (salt or ash) on alloy. The greatest corrosion is always ...

High temperature oxidation and hot corrosion are the serious problems in aircraft, marine, industrial and land-base gas turbines. It is because of the usage of wide range of fuels coupled with increased operating temperatures, ...

Hard coatings of transition metal nitride materials (TiN, CrN, TiSiN, CrSiN, etc) are used in tribological applications due to their remarkable physical and mechanical properties such as high hardness, high melting point, ...

Materials degradation at high temperatures is a serious problem in several high tech industries. Power plants are one of the major industries which encounter severe corrosion problems resulting in the substantial loss. The ...

Shape memory alloy (SMA) thin films of Nickel-Titanium (NiTi) have attracted much attention in recent years as intelligent and functional materials due to their unique properties i.e. superelasticity, and shape memory ...

Silicides are a new class of engineering materials, which offers the advantages of a ceramic as well as of a metal. Out of a large number of silicide compounds known, MoSi2 has been proposed as a model material for high ...
