熱噴涂設(shè)備（噴鋅機(jī)，噴鋁機(jī)，噴鋅鋁合金機(jī)）系列

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

·熱噴涂系列過(guò)程：以某種熱源將噴涂材料（線材或粉材）加熱，受熱的材料形成熔融或半熔融狀態(tài)的微粒，這些微粒以壓縮空氣為動(dòng)力以一定的速度沖擊并沉積在基體表面上，形成具有一定特性的噴涂層。

·以提供熱源的不同，可分為燃燒法和電熱法。前者包括燃燒火焰噴涂、爆炸噴涂及高速火焰噴涂（HVOF）；后者包括電弧噴涂及等離子噴涂（又分常壓等離子噴涂與水穩(wěn)等離子噴涂）。噴涂工藝對(duì)涂層產(chǎn)生重要影響的是噴涂溫度（嚴(yán)格的說(shuō)，是溶滴沖擊基體表面時(shí)的溫度）和溶滴沖擊表面的速度。

·斯特爾熱噴涂系統(tǒng)主要用于鐵塔、燈桿、橋梁、水閘們、船舶等結(jié)構(gòu)件大面積長(zhǎng)效防腐及造紙烘缸、印刷輥、曲軸等工件的表面磨損的噴涂修復(fù)，還適用于電容、電瓷行業(yè)的電極噴涂等。

·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.

◆涂層功能 Coating function

依據(jù)美國(guó)F.N.LONGO對(duì)熱噴涂涂層的分類方法，涂層按功能可分為：

1、耐磨損涂層。包括抗粘著磨損、表面疲勞磨損涂層和耐沖濁涂層。其中有些情況還有抗低溫（<538C）磨損和抗高溫（538～843C）磨損涂層之分。

2、耐熱抗氧化涂層。該種涂層包括高溫過(guò)程（其中有氧化氣氛、腐蝕性氣體、高于843℃的沖蝕及熱障）和熔融金屬過(guò)程（其中有熔融鋅、熔融鋁、熔融鐵和鋼、熔融銅）所應(yīng)用的涂層。

3、抗大氣和浸漬腐蝕涂層。大氣腐蝕包括工業(yè)氣氛、鹽性氣氛、田野氣氛等造成的腐蝕；浸漬腐蝕包括飲用淡水、非飲用淡水、熱淡水、鹽水、化學(xué)和食品加工等造成的腐蝕。

4、電導(dǎo)和電阻涂層。該種涂層用于電導(dǎo)、電阻和屏蔽。

5、恢復(fù)尺寸涂層。該種涂層用于鐵基（可切削與可磨削的碳鋼和耐蝕鋼）和有色金屬（鎳、鈷、銅、鋁、鈦及他們的合金）制品。

6、機(jī)械部件間隙控制涂層。該種涂層可磨。

7、耐化學(xué)腐蝕涂層。化學(xué)腐蝕包括各種酸、堿、鹽，各種無(wú)機(jī)物和各種有機(jī)化學(xué)介質(zhì)的腐蝕。

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.
