Since the second half of the 20th century it has been great challenges in engines development, with more compact vehicles and the use of new lubricant oil and fuel technologies associated to increased power, performance and consequently the reduction of the emissions levels. By tribology view, science and technology that study the interaction between surfaces in relative motion, it means an increase of specific loads, speeds and temperatures in engine components submitted to friction (1).
This work studies the behavior of lubricant oil SAE 15W40 between tribological pairs of three different surface treatments technologies against a standard ring of gray casting iron. It was used a test bench with block on ring geometry modified and unidirectional sliding movement utilized to evaluate the wear mechanisms, friction and lubrication of the piston ring-cylinder bore of internal combustion engines.
The tribological bench tests showed the variation of structural interfaces and functions parameters, without the utilization of fuel and consequently not presence of combustion. The results of the lubricant oil analysis were attended through statistics software that determines the main effect and interactions, as well as the evaluation of the worn surface appearance for different operating conditions.
