wear prevention
1.NiCr coating produced by arc-spraying technology on the materials surface exhibited excellent high-temperature corrosion resistance and good wear-resistant features. So these coatings can be used in the prevention of converter draught hood in high-temperature environments and resistance to wear for the waste cooling wall tubes of converter draught hood, and they might rapidly lead to the industrial applications.
2.Cause analysis and prevention countermeasures on the wear of thrust bush of the main oil pump of 300?MW steam turbine
3.The beautiful source shoe industry founds in the beginning of 1980s, has been through repeatedly more than 20 years endeavor, already formed suitable scale specialized production a series of major industries, at present introduces world most advanced automatic EVA to project the disposable foaming shaper now, take the leisure, facile, the skid prevention, wear-resisting and so on as the characteristic, made the high grade the product.
