In this paper, W-Mo-Y co infiltration were carried out on the surface of 45 steel wedge components by plasma solid-state surface metallurgy technology. The phase, hardness, friction and wear properties before and after W-Mo co infiltration and W-Mo-Y co infiltration were systematically studied. The diffusion kinetics such as diffusion coefficient and diffusion activation energy were calculated by Fick's second diffusion law, and the effect of Y on the diffusion of W and Mo atoms in the infiltrated layer was obtained. It is found that the addition of rare earth Y element increases the diffusion coefficient of W and Mo atoms and reduces the diffusion activation energy, which has a certain catalytic effect. And the W-Mo-Y co infiltration significantly improves the surface hardness and wears resistance of the parts and prolongs the service life of the parts.

Wear, corrosion and fatigue are among the most important mechanisms that lead to surface damage, which, ultimately, leads to failure of the components. There is an increasing demand for reducing failures and the related costs due to wear and surface shortcomings of heavily loaded engineering components. Thus, application of surface technologies gives a great potential for saving resources and providing improved technology. The presented research work involves characterization of a duplex treated i.e. plasma nitrided (at two different temperatures 520 °C, 550 °C) and PVD coated – X42Cr13/W plastic mould tool steel with special emphasis on the ball-on-disc wear behaviour of tested specimens. The objective is to study and evaluate the effect of different nitriding treatments prior to coating on the wear behaviour of specimens having different surface preparations. Also, it has been established that duplex treatment (plasma nitriding + physical vapour deposition [PVD] coating) gives better and improved properties as compared to individual treatments.

In order to break the limitation of plasma nitriding technology, which can be applied to a few non-metallic gaseous elements, the "Double Glow Discharge Phenomenon" was found and then invented the "Double Glow Plasma Surface Metallurgy Technology". This double glow plasma surface metallurgy technology can use any element in the periodic table of chemical elements for surface alloying of metal materials. Countless surface alloys with special physical and chemical properties have been produced on the surfaces of conductive materials.By using double glow discharge phenomenon, a series of new plasma technologies，such as the double glow plasma grapheme technology, double glow plasma brazing technology, double glow plasma sintering technology, double glow plasma nanotechnology, double glow plasma cleaning technology, double glow plasma carburizing without hydrogen and so on, have been invented.A very simple phenomenon of double glow discharge can generate about 10 plasma innovation technologies, which fully shows that there is still a lot of innovation space on the basis of classical physics. This paper briefly introduces the basic principles, functions and characteristics of each technology. The application prospects and development directions of plasma in metal materials and machinery manufacturing industry will also be discussed.
