Impregnation & Infiltration • Impregnation - when oil or other fluid is permeated into the pores of a sintered part – oil-impregnated bearings gears and similar components – An alternative application is when parts are impregnated with polymer resins to create a pressure tight part • Infiltration - An operation in which the pores
Abstract—A model of the melt impregnation of metal powder under low-frequency vibration is presented in the form of mathematical dependences The influence of factors such as the powder dispersity its wetting with the melt melt viscosity and conditions and parameters of the vibration treatment are considered The
