FORMATION OF SELF-FLUXING ALLOY SPRAYED DEPOSIT

摘要

PURPOSE:To offer a method for forming a self-fluxing allay sprayed deposit in which its wear resistance and corrosion resistance lie in a high area for practical use without executing reheating treatment after thermal spraying which has been indispensable heretofore. CONSTITUTION:At the time of thermal-spraying self-fluxing alloy powder, the pressure of oxygen and fuel gas are produced each under 0.29 to 0.98MPa and the combustion flame of combustible gas is used as a heat source, by which the flow velocity of the flame is increased and high kinetic energy is given to flying particles, and the above particles are densely laminated to obtain a deposit having excellent film quality.
