Abstract
A composition and process are disclosed for constructing a diesel engine element, such as for example, a valve guide which will withstand the friction of various tribological locations in a diesel engine when operating the engine at elevated temperatures and/or on alternative fuels. The composition is one of a glass,glass-ceramic, and mixtures thereof matrix having graphite particles. In the process, a unitary element is formed from the mixture and thereafter is sintered for a time and temperature sufficient to obtain a preselected density.
