Description

用于进行热喷涂工艺的设备 Apparatus for thermal spraying process

背景技术 Background technique

热喷枪被用于在基体上热喷涂在高能流动物流中输运的涂层的工艺中.热喷涂还已称为火焰喷涂、金属化、高速氣燃料热喷涂 Thermal spray gun is used in a thermal spray coating on a substrate in a high energy transport in the process flow stream. It has also been referred to as thermal spraying flame spraying, metallization, thermal spraying high velocity gas fuel

(HV0.F)和高速空气燃料热喷涂(HVA,F).涂层材料通常为金属、陶瓷或水泥型(Cement-type)材料.高能流动物流通常包括用于在高速下将涂层材料推进和输运至基体标靶的燃烧气体.涂层材料可以以声音在环境空气中的速度或更高的速度行进. (HV0.F) thermal spraying and high velocity air fuel (HVA, F). The coating material is typically a metal, ceramic or cement type (Cement-type) materials for high energy flow stream generally comprises advancing at high speed the coating material and transporting the substrate to the target combustion gases. the coating material may be traveling at the speed of sound in the ambient air speed or higher.

通过热喷涂施加的涂层被认为主要通过由于涂层微粒在高速下与基体表面碰撞所致的机械粘结作用而粘附到基体上.还理论化的是, 当涂层微粒撞击基体时,以高速涂层微粒轰击基体导致涂层微粒的一些动能转化成热.这种来自转化的动能的热被认为有助于将涂层材料连结到基体上,有时被称作"微连结". By thermal spray coating that is applied mainly adhered to the substrate by mechanical action due to the bond coat particles collide with the substrate surface at high speed due to is also theorized that, when the coating particles impact the substrate, microprojectile bombardment at a high speed coating the substrate causes some kinetic energy into fine particle coating heat. this heat from the conversion of kinetic energy is considered to contribute to the bond coating material onto a substrate, it is sometimes referred to as "micro link".

通常通过燃料和氧化刑燃烧所致的高温火焰喷射提供热喷涂燃烧气体,所述燃料和氣化刑的燃烧释放热量并产生高温受压气体流.热喷枪有时利用燃烧组分,或反应物,例如氧气和丙烷、氣气和氢气、 氣气和煤油以及煤油和空气.燃料和氣气源被注入燃烧区域内,在所述区域中所述燃料和氣气源在压力和温度下发生燃烧反应以产生高温受压气体流,所述气体流被从燃烧区域中引导出来并进入高速流动物流内.涂层材料,例如金属、陶瓷或水泥,被引入流动物流内,高温受压气体被从燃烧区域引导出来且沿着流动喷嘴流动以将涂层材料微粒推进入标把基体内.通常情况下,在离开热喷枪的高速流动物流中出现多个马赫锥以表示高温受压气体在几倍于声速的速度下朝向标靶基体行进. Induced by normal combustion of fuel and oxidizing flame spray punishment temperature combustion gas to provide thermal spray, heat released by combustion and gasification of the fuel penalty and high temperature pressurized gas stream by combustion thermal spray gun may component, or reactant, e.g. oxygen and propane gas and hydrogen gas, kerosene, and the kerosene and gas gas and air. the fuel gas is injected into the combustion gas source region, said source of fuel gas and air in the combustion reaction zone at a pressure and temperature to produce a high temperature flow of pressurized gas, the gas flow is directed from the combustion zone and into the high velocity flow stream. the coating material, such as metal, ceramic or cement, is introduced into the flow stream, high temperature pressurized gas is directed out of the combustion zone and the flow along the nozzle flow to push the coating material particles enter the matrix labeled. typically, a plurality of the Mach cone occurs at high flow stream leaving the thermal spray gun to a high temperature pressurized gas velocity expressed in several times the speed of sound under travels toward the target substrate.

然而,在热喷枪搮作的高温条件下,热损耗可较高.此外,燃料和氧气消耗速度可较高,这增加了操作花费.因此,产生了对具有改进的搮作效率的热喷枪的需要. However, at a high temperature thermal spray gun for Li, the heat loss can be higher. In addition, fuel and oxygen consumption rate can be higher, which increases operating expense. Thus, a thermal spray gun having an improved operating efficiency Li of need.
