美国TAFA公司正在开发一种增加钢结构煤车抗腐耐磨性能、延长使用寿命的方法。此项技术是在车辆上电弧喷镀厚7mil(1mil=25.4μ)的纯铝层。这种防腐方法成本低,既能用于新造车又能用于美国480000辆运用车。开发这种防护方法是由于1984年发现两辆1962年造的喷铝煤车,经22年运用后没有因腐蚀或磨蚀引起车体钢结构的损坏。 TAFA公司推荐的煤车防腐,特别是运输高硫煤的车辆抗腐耐磨的方法是: ·喷水清洗:水速6705.6m/s,喷嘴压力为2380kgf/cn~2:
The United States TAFA company is developing a way to increase the anti-corrosion wear-resistant steel performance coal car, extend the service life of the method. The technology is arc-sprayed on vehicles with a thickness of 7mil (1mil = 25.4μ) pure aluminum layer. This method of anticorrosion is low cost and can be used both for new vehicles and for more than 480,000 vehicles in the United States. The development of this method of protection was due to the discovery in 1984 of two 1961 pulverized coal-fired vehicles that, after 22 years of operation, did not cause damage to the steel structure of the vehicle due to corrosion or abrasion. TAFA recommended car anti-corrosion, especially the transport of high-sulfur coal vehicles anti-corrosion and wear-resistant methods are: Water spray cleaning: water velocity 6705.6m / s, nozzle pressure of 2380kgf / cn ~ 2:
