The influence of iron powder cladding with nickel on properties of sintered materials

Resumo

This article discusses sintering of sprayed iron powder cladded with nickel. Mechanisms of packing and formation of structural characteristics and mechanical properties as a function of sintering temperature, composition, application procedure, and conditions of thermal treatment of 0.5–2.0% Ni coatings are determined. Cladding upon combined use of post reduction of coatings with sintering makes it possible to reduce the porosity by 2–3% and to improve the mechanical properties of materials by 1.4–1.9 times in comparison with composites based on micropowder blends.
