Spray materials ( powder or wire) are melted or partly melted by flame, electric arc or plasma plume and propelled onto the substrate by compressed gas. 热喷涂是通过火焰、电弧或等离子体等热源将某种线状或粉末状的材料加热至熔化或半熔化状态,并通过气流吹动使其雾化高速喷射到基体表面,以形成喷涂层的表面加工技术。
Plume is an important basis reflecting the working performance of the electric thruster. The methods of langmuir probe diagnosing plume plasma parameters divide into three ways: single probe method, double probe method and triple probe method. 羽流是反映电推力器工作性能的重要依据,Langmuir探针诊断羽流等离子体参数有三种方法:单探针法、双探针法和三探针法。
