Thermal spray method for producing glass mold plungers. |
摘要 |
<p>Manufacture of glass mold plungers utilizes a thermal spray gun (10) having combustion chamber (82) with an open channel for propelling combustion products into the ambient atmosphere at supersonic velocity. The method comprises injecting into the chamber a combustible mixture of combustion gas and oxygen at a pressure in the chamber of at least two atmospheres above ambient atmospheric pressure, feeding into the chamber a powder comprising self-fluxing alloy particles, and combusting the combustible mixture in the chamber means (82) whereby a supersonic spray stream containing the powder is propelled through the open channel. The spray stream is directed toward a glass mold plunger substrate such as to produce a coating thereon which is ground and polished. The coating may be fused prior to grinding.</p> |
