MIL-STD-869C, MILITARY STANDARD: FLAME SPRAYING (20 OCT 1988) [NO S/S DOCUMENT]., This standard covers the materials, procedures, and equipment for flame spraying of parts. Flame spraying is defined as the process of melting materials in a heating zone and propelling them in the molten state onto a part to form a coating. This process can be applied to build up worn areas on parts, for abrasion resistance and/or corrosion protection. It is not intended to rebuild damage by nicks, gouges, etc., without building an entire area.【英文标准名称】:Photovoltaicdevices-Part10:Methodsoflinearitymeasurement
