To increase the resistance to wear and corrosion of the surface layers made from steel with 0.45% C, multilayer deposition was tested by injection of powder with chemical composition of 8.9% Cr, 4.5% Fe, 5.1% B, 2, 4% ...

Multilayer cladding by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B, 2.4% Al, 0.6% Cu, Ni rest as chemical composition, in melted bath by a continuous wave CO2laser connected to x-y-z coordinate table was tested in ...

The paper presents the structural changes that appeared in steel for deep drawing, as a result of cold rolling and of recrystallization thermal treatment. The research was conducted on samples taken from the rolled strap, ...

For the purpose of studying the possibilities of increasing the wear resistance, specimens of three steels with 0.2%C, 0.46%C and 1%C were surface alloyed with reinforcement from overlapping pastes with green SiC hard ...

The objective of the research is development and study of a new ecologically friendly and technologically advanced method for introduction of carbon during sintering of low alloyed iron powders ASC 100.29. The method is ...

The article presents how to obtain porous bronze products using copper - based powder by powder metallurgy methods. The formation of tablets was done by free pouring the spherical powder into the mould, followed by their ...

The paper presents the investigation by conductive-atomic force microscopy (C-AFM) of the variation of the local conductivity and topography of the transparent ZnO thin films deposed onto soda lima glass substrates by ...

The autocatalytic reduction method (electroless method) was applied to obtain the Ni-P layers with different P contents. Nickel sulfate was used as nickel ion source and as reducing agent the sodium hypophosphite. The ...

In order to rise the wear and corrosion resistance of 0.45% C superficial steel layers, a multilayer coating was tested by injection of powder with 88.3% Cu; 9.5% Al; 2.2% Fe in melted bath by CO2 continuous wave laser. ...

In recent years, different types of titanium alloys have been investigated with the aim of using materials in biomaterials field, and Ti-Mo system alloys are very promising materials. Alloying titanium with biocompatible ...
