| Sumario: | In article the technique and results of researches of processes plasma-jet powder hard-facing with the subsequent electric resistance rolling of antifrictional and wearproof coatings made from nickel and bronze powders is resulted. It is shown, that speed of plasma-jet powder hard-facing influences on bases distortion, and also structure (in particular, on residual porosity) of antifrictional and wear-resistant coatings material, including their hardness and strength. The electric resistance rolling realized after overlaying welding, at the expense of flattening of available hollows in the material of a powdered coating, can reduce the residual porosity, raise hardness and strength of coatings to level analogous, gained at rather small (in two and more times) speeds of plasma-jet powder hard-facing. |
