The lubrication gradient material (LGM) was used for making sliding shoes of automotive air-conditioning compressor. Average friction coefficient of the sliding shoes treated with LGM decreases 39. 5% ,the average friction power is 51. 3% lower than before,its service life increase 1.5-3.4 times. Original LGM acceptance criteria and technique standard in quality system were formulated. 1.044 million vehicles were accumulatively assembled with LGM compressor from the year of 2007, including the brands of Shanghai Volkswagen, General Motor and SAIC motor. A successful pioneer of industrialization of intellectual property was created in China heat treatment industry.

The mist gas of aluminum chloride (AlCl3) was produced at low pressure in vacuum chamber according to its change nature. Dozens micron of the aluminizing layer of 10 and 45 carbon steels were obtained through physical-chemical reaction from mist gas at 620 °C. Aluminizing temperature of mist gas is the lowest among all the methods.
