| Popis: | Tungsten can be VPS formed to 99% density in furnace retort shapes. The VPS tungsten microstructure is dependent on substrate temperature. Material deposited below 815 °C (1500 °F) displayed a splat structure, whereas material deposited above 1150 °C (2100 °F) was recrystallized. The VPS process can be used to make transitions from alumina to a gradient layer with a continuously increasing proportion of tungsten to a pure tungsten layer in a single spray operation. |
