Abstract

PURPOSE:To improve resistance to abrasion by a method wherein the matrixes of the oil ring to be combined with the cylinder liner in a sliding relation therewith are given specified compositions and hardnesses. CONSTITUTION:Two pieces of slide rails 1 are supported by a space expander 2 in the axial and radial directions thereof and the outer peripheral surface 11 of the side rail is slided with the inner peripheral surface 31 of the cylinder liner. Said side rail 1 consisting of a matrix, of which base organization is a tempered martensite, has a total hardness of HRC38-43 and is a stainless steel of the martensite type having a weight ratio described in the table (I). On the other hand, the cylinder liner has the composition described in the table (II) and a carbide having a high hardness is distributed in the base of martensite in an area ratio of 5-25% while the difference of the hardness between the base and the carbide is HV300 or more.
