Optimization of technological parameters of part blanks centrifugal reinforcement with two mutually perpendicular revolutionary axes of the mold

Abstract

This paper presents the research results of technological parameters of centrifugal reinforcement of steel parts
working area such as revolution bodies by tungsten carbide particles, specific density of which is greater than that
of the steel, by mathematical planning of experiment. The authors have received polynomial regression models of
the dependence of tungsten carbide particles concentrations and part blanks durability on the technological parameters
of centrifugal reinforcement with two mutually perpendicular axes of the mold revolution: mold rpm
around horizontal and vertical axes, the heating temperature of a ceramic form and reinforcing particles. The optimum
values of technological parameters are determined and it is found that the magnitude of the concentration of
tungsten carbide particles and part blanks wear resistance are influenced rather by kinematic parameters of the
centrifugal reinforcement than the temperature.
