in this work the effects of various methods of agitation on the properties of electroless ni-p-mos2 composite coatings were investigated. magnetic stirring as well as purging the solution with gas (air, oxygen, nitrogen) were used. plating rate, chemical composition, mos2 distribution, and hardness of the deposit were measured. topography of coating was studied with metallography and scanning e...

Pure aluminium poses inferior properties that limit its use in load-bearing applications. Reinforcing multiwall carbon nano-tube (solid lubricant) and graphene to matrix offers better (antifriction, hardness, wear resistance) composites for such A stir casting processing route is employed prepare the hybrid composite (aluminium-multiwall nanotube-graphene Al-MWCNT-GR). The Taguchi L16 experimen...

Marine nuclear power platforms can continuously supply electricity and fresh water for marine resource exploration surrounding islands. China’s first platform uses a soft yoke multi-joint connect mode as the mooring positioning device. When needs repair, maintenance, fuel replacement, or different operation area, disconnect must be carried out. The traditional process consists of four stages: c...

In this work, antifriction and antiwear capabilities of hexagonal boron nitride nanoparticles (h-BN) or graphene nanoplatelets (GnP) as additives a polyalphaolefin neat oil (PAO 40) were studied at pure sliding conditions. For purpose, eight PAO 40 nanodispersions prepared: four with h-BN others based on GnP. The mass concentrations these dispersions are 0.25, 0.50, 0.75 1.00 wt% 0.05, 0.10. 0....

The object of research is the hydrophobization a coating based on styrene-acrylic copolymer and cellulose acetate butyrate with pyrogenic silicon dioxide. hydrophobicity or hydrophilicity surface depends mainly chemical structure its roughness. A relief hydrophilic will be wetted much more easily than flat same material, vice versa – an increase in roughness hydrophobe accompanied by pronounced...

The tribological properties of matrix and skeletal titanium carbonitride composites were studied in dry friction conditions air. Experiments on wetting the TiCN–Cr3C2 composite by nickel–chromium alloys copper using sessile drop method performed to choose composition ascertain whether samples could be produced impregnation porous skeleton. experiments showed that nickel its formed a low contact...
