ABSTRACT:
A slidable ceramic member includes a base of a sintered ceramic material which is a compound including silicon (Si) as a constituent element, the base having a sliding surface, and a coated layer covering the sliding surface of the base, the coated layer comprising a compound of elements, such as barium (Ba) and calcium (Ca), belonging to group IIa of the periodic table, silicon (Si), and oxygen (O). The slidable ceramic member is used as a slidable component of a heat engine such as a cylinder liner or a piston ring which is subjected to repeated thermal stresses. Such a slidable ceramic member is manufactured by placing powder of a fluoride including elements belonging to group IIa of the periodic table on a surface of a base, and heating the base while rubbing the powder against the surface of the base, whereby the silicon (Si) contained in the base and the group-IIa elements contained in the powder can react with each other, thereby forming a slidable layer on the surface of the base.
