USE OF CHEMICAL SYNTHESIS OF NANODISPERSE MODIFIERS AT INDUCTION HEATING OF FURNACE CHARGE ON THE BASIS OF POWDERS TIN BRONZE FOR HARDENING AND INCREASE OF TRIBOTECHNICAL PROPERTIES OF THE FUSE-ON COVERINGS
Abstract
Through the example of an induction centrifugal overlay welding of furnace charge from powders of tin bronze (90–100% of total lump) and an intermediate product (boehmite) the possibility of hardening of the coverings by means of chemical synthesis of nanodisperse modifiers (Al2O3) in the course of heating and transition to a liquid-phase condition of coating material is shown. Reasons about necessity to use in furnace charge of an intermediate product of larger fraction, than the nanodisperse modifiers synthesized from it are provided, if such furnace charge is produced by mechanical mixing and is affected by centrifugal forces. Results of metalgraphical researches and tribotechnical testing of the coverings received from powders of tin bronze and a boehmite in the course of an induction centrifugal overlay welding on the temperature conditions promoting synthesis a-Al2O3 are given.
