Technical characteristics
☆主要特點:

1.The protective layer compensates selectively worn surfaces, thus optimizing the fitting clearances and restoring the original dimensions of the worn parts.
2.There is no discernible demarcation between the protective layer and the original metallic substrate owing to their metallurgical-chemical bonding, and there is no spalling effect.
3.The protective layer with superlubricity behavior greatly decreases energy losses due to friction.
4.The protective layer with super surface smoothness improves greatly behavior of pressurized seal in power machinery, thus improving combustion efficiency and alleviating emission pollution.
5.The functionality of the ART treatment decreases by 50% if the engine wear surpasses 70%. So application of the ART treatment should be executed after normal maintenance to assure application effectiveness.
6.Refurnish the engine oil timely and routinely. But no oil change is needed within the initial 20,000 kilometers of driving.
7.It is strongly recommended that certified oil filters be selected and installed which would otherwise damage the ART treatment effectiveness.
