Microplasma deposition apparatus and methods

摘要

Microspray apparatus and methods involve injecting powdered material into a plasma gas stream (21). The material comprises first and second component powders. The second powder is a majority by the weight of the powdered material. The first powder acts as a melting point depressant. The first and second powders may have similar compositions but with the first powder including a greater quantity of a melting point depressant element.
