Abstract
The present invention pertains to steel articles having improved wear and friction properties and the method of producing these articles. A steel surface containing relatively high levels of nitrogen and having a surface film containing carbon is implanted with high energy ions. Overlapping layers enriched in carbon and nitrogen are formed beneath the surface and provide the steel with a surface that has improved wear and friction characteristics.
