Abstract: A high strength cast iron material for application in heavy duty diesel engines with Pa peak cylinder pressure greater than 240 bar is disclosed, the material a ductile material austempered to get a ausferrite matrix structure with higher mechanical properties than conventional cast iron materials available by using a designed low cost alloying cast material with heat treatment. Furthermore, the cylinder liner may be formed using novel heat treatment and/or fine honing processes to improve the properties thereof.

Abstract: A cylinder liner is disclosed, the cylinder liner having a smoother internal surface of an internal side than known cylinder liners. The internal surface having at least one of a reduced peak height of (Rpk) of ?0.25 ?m, a core roughness (Rk) of about 0.2 ?m to about 0.6 ?m, a reduced valley depth (Rvk) of about 1.2 ?m to about 2.5 ?m, a material ratio (Mr1) of ?10%, and a material ratio (Mr2) of about 70% to about 90%.

Abstract: A cylinder liner with high strength and wear resistance and a manufacturing method thereof. The composition (% by mass) of the cylinder liner is as follows: C: 3.0-3.3%, Si: 2.0-2.3%, P: 0.3-0.6%, S: <0.1%, Mn: 0.3-0.6%, Mo: 0.1-0.3%, Nb: 0.08-0.15%, and the balance Fe. The structure of the cylinder liner is phosphorus-containing acicular ferrite and carbon-rich austenite, wherein the phosphide eutectic is no less than 3%. The cylinder liner has a hardness of HRC38-43, Rm>400 MPa, high strength and good wear resistance, solves the problem of pearlite cylinder liner with low wear resistance and cast bainite with bad corrosion resistance.
