Over the last 20 years, because of their superior hardness, chemical stability, and outstanding oxidation barrier, many coating systems have now been extensively researched using various deposition processes employed for wear-resistant protection [...]

• GNP incorporated in alumina matrix to deposit composite coatings via SPS. Raman analysis confirmed retention of as-processed coatings. Improved mechanical and tribological properties achieved for Wear mechanisms monolithic coating were revealed. Graphene possesses high fracture toughness excellent lubrication properties, which can be exploited enhance performance systems utilized combat wear....

In this research, tribological characteristics of Ni-P electroless coating and double-layered Ni-P/Ni-B electroless coating were studied. For this purpose, Ni-P electroless coating with 25 μm thickness was initially applied to the surface of steel Ck45 samples; then, a double-layered Ni-P/Ni-B electroless coating, including inner layer of Ni-P with 15 μm thickness and outer layer of Ni-B with 1...

The possibility of using polymer concrete for metal cutting machine beds is analyzed. A comparison the structures made and cast iron made. frequency body determined. An analysis stress–strain state under static loads carried out. To increase resistance to wear, it proposed spray frames are by gas–thermal method. installation thermal spraying guide given. optimal parameters guides established ca...

In this research, B4C-Ni cermet coating was sprayed on the surface of 4130 steel from B4C and Ni feed-stockpowders using high velocity oxy-fuel (HVOF) method. In order to characterize the tribological behavior of thecoating, ball on disk wear tests were done at the ambient temperature and under the loads of 1, 3 and 5 N.Phase analysis of the coating after spraying was studied ...
