    摘要: A composition and method for providing a silicon-nitrogen surface on metals wherein is reacted a source of silicon, a source of ammonium ions, an alkali metal hydroxide in an aqueous medium to produce an electrolyte solution comprising a complex ion mixture. The electrolyte solution can be used to deposit a silicon surface on conductive substrates. The electrolyte solution can be dehydrated in a hydrocarbon medium, thus providing novel materials for use as lubricating oil additives and as fuel additives. The fuels and lubricants can be used as carriers for depositing the complex to form a silicon/nitrogen and silicon/nitrogen bimetallic surfaces on metal surfaces including, but not limited to, metals in the combustion chamber either through an aqueous phase or through a hydrocarbon phase. These new silicon/nitrogen surfaces may significantly reduce coefficient of friction, smooth the flame front, reduce corrosion, enhance fuel economy, and reduce hydrocarbon emissions when used in internal combustion engines.
