热喷涂设备（喷锌机，喷铝机，喷锌铝合金机）系列

Thermal spraying equipment (spraying zinc machine, spraying aluminum machine, spraying  injection machine spraying zinc alloy machine) series

·热喷涂系列过程：以某种热源将喷涂材料（线材或粉材）加热，受热的材料形成熔融或半熔融状态的微粒，这些微粒以压缩空气为动力以一定的速度冲击并沉积在基体表面上，形成具有一定特性的喷涂层。

·以提供热源的不同，可分为燃烧法和电热法。前者包括燃烧火焰喷涂、爆炸喷涂及高速火焰喷涂（HVOF）；后者包括电弧喷涂及等离子喷涂（又分常压等离子喷涂与水稳等离子喷涂）。喷涂工艺对涂层产生重要影响的是喷涂温度（严格的说，是溶滴冲击基体表面时的温度）和溶滴冲击表面的速度。

·斯特尔热喷涂系统主要用于铁塔、灯杆、桥梁、水闸们、船舶等结构件大面积长效防腐及造纸烘缸、印刷辊、曲轴等工件的表面磨损的喷涂修复，还适用于电容、电瓷行业的电极喷涂等。

·Thermal spraying series process: Add some heat source and to heat up the spraying materials(Wire or powder materials), heated material form melting or half melt condition of particles, These particles are power by compressed, to certain speed for the impact and deposition in the matrix surface, form a spray coating with some characteristics.

·To the different provide between heat source it can be divided into burning method and heating method. The former includes combustion flame spraying, explosion spraying and the flame spraying (HVOF); The latter include arc spraying and plasma spraying (is divided into atmospheric plasma spraying and plasma spraying water stability). Spraying process have an important impact on the coating is that spraying temperature (Strict said, it is the temperature of dissolve drops the matrix surface of the impact) and dissolve the speed of the impact drops surface.

·Stel hot spraying System, which is used for light pole, Bridges, tower, the locks, shipbuilding and other structural long-term anti-corrosion and paper dryer, printing roll, crankshaft etc of workpiece surface wear spraying repair, also applies to capacitor, electroceramics electrode coating industry.

◆涂层功能 Coating function

依据美国F.N.LONGO对热喷涂涂层的分类方法，涂层按功能可分为：

1、耐磨损涂层。包括抗粘着磨损、表面疲劳磨损涂层和耐冲浊涂层。其中有些情况还有抗低温（<538C）磨损和抗高温（538～843C）磨损涂层之分。

2、耐热抗氧化涂层。该种涂层包括高温过程（其中有氧化气氛、腐蚀性气体、高于843℃的冲蚀及热障）和熔融金属过程（其中有熔融锌、熔融铝、熔融铁和钢、熔融铜）所应用的涂层。

3、抗大气和浸渍腐蚀涂层。大气腐蚀包括工业气氛、盐性气氛、田野气氛等造成的腐蚀；浸渍腐蚀包括饮用淡水、非饮用淡水、热淡水、盐水、化学和食品加工等造成的腐蚀。

4、电导和电阻涂层。该种涂层用于电导、电阻和屏蔽。

5、恢复尺寸涂层。该种涂层用于铁基（可切削与可磨削的碳钢和耐蚀钢）和有色金属（镍、钴、铜、铝、钛及他们的合金）制品。

6、机械部件间隙控制涂层。该种涂层可磨。

7、耐化学腐蚀涂层。化学腐蚀包括各种酸、碱、盐，各种无机物和各种有机化学介质的腐蚀。

Coating can be divided in function according to the US F.N.LONGO of method that the classified method of thermal spraying coating.

1. Wear resistance coating. Including resistance to stick with wear, wear coating surface fatigue and resistance to blunt turbidity coating. Some of them have difference such as fight microtherm wear(<538C) and high temperature resisting wear coating(538~843C).

2. Heat resistant antioxidant coating. This coating process application of coatings including high temperature( There are oxidation atmosphere, corrosive gas, higher than 843℃ of erosion and thermal barrier) and molten metal process(There are melting molten aluminum, zinc, iron and steel, melting molten copper).

3. Atmospheric corrosion resistance and dipping coating. Atmospheric corrosion caused by corrosion including industrial atmosphere, atmosphere, atmosphere of salt field, etc; Dipping corrosion caused by corrosion including drinking water, the drinking water, hot water, salt water, chemical and food processing, etc.

4. Conductivity and resistance coating.The coating used for electrical conduction, resistance and shielding.

5. Restore size coating. The coating used for some products made by iron (Carbon steel and corrosion resistant steel that can but cutting and grinding) and non-ferrous metal (Nickel, cobalt, copper, aluminum, titanium and other alloy).

6. Mechanical components clearance control coating.The coating can be ground.
