Titanium compound with superior wear resistance

Titanium pigment to a number of areas from aerospace alloys have been widely known magical elements, perhaps in turn has a new purpose. American Afton Chemical Corporation and the National Institute of Standards and Technology (NIST) materials scientist, 23, said they found that the addition of the titanium compound into the oil (lubricant), the wear on the vehicle's engine can be formed easily damaged parts of the surface nano-coating to improve the wear resistance of oil. If the titanium compound in the future be able to replace oil in the current anti-wear additives, will be able to get environmentally friendly oil.
Engine oil is a complex mixture of mucus, wherein up to 20% of the ingredients for a particular additive, the purpose is to enhance the characteristics of the oil, such as viscosity and stability, to reduce engine wear and the formation of grease. Over the years, the oil antiwear performance mainly depends on the phosphorus compound, especially ZDDP. The compound forms a thin film on the polyphosphate engine parts, thereby reducing the wear rate components. But phosphorus is a chemical substance harmful to the vehicle catalytic converters, will reduce the efficiency of the catalytic converter and shorten its life. Therefore, the industry has long been looking for ways to replace or less of the substance or use of ZDDP. But never did find a solution.
