摘要： A method for manufacturing an apex seal for a rotary piston engine comprising steps of preparing an apex seal blank made of ceramic material, and applying a high energy heating radiation to the sliding surface of the apex seal blank to form a roughened and porous structure on the surface portion of the apex seal blank. The high energy heating radiation is desirably applied to the apex seal blank under a non-oxidizing atmosphere so that an oxidization of the components of the ceramic material can be prevented.
