摘要： A prehardened valve seat insert and a process for forming a prehardened valve seat insert for insertion into a cylinder head or an engine block of an internal combustion engine. The process comprises the steps of (a) forming the valve seat insert; (b) precision machining the valve seat insert to precise tolerances so that the valve seat insert can be installed in one of the cylinder head and the engine block without the need for additional seat machining; and (c) treating the valve seat insert to form a wear resistant surface layer prior to inserting the valve seat insert into one of the cylinder head and the engine block.

摘要： A cobalt-rich wear resistant and corrosion resistant alloy comprises in weight %, 0.5 to 1.2% C, 0.6 to 2.1% Si, 17 to 24% Cr, 27 to 38.5% Fe, 1.4 to 20% W, 3.8 to 9.7% Mo, less than 1% Ni and balance Co. A preferred cobalt-rich alloy comprises in weight %, 0.5 to 0.9 C, 0.75 to 1.15% Si, 17.5 to 20.5 Cr, 27.0 to 32.0 Fe, 12.5 to 16.5 W, 6.25 to 8.25 Mo, 0.45 to 1.00 Ni and balance Co. The alloy preferably has a microstructure free of primary carbides and comprises up to about 50% by volume eutectic reaction phases in a solid solution matrix. The solid solution matrix is an αFe-αCo face-centered cubic solution with W, Cr and Mo as solute elements and the eutectic reaction products comprise a (Co,Cr)7(W,Mo)6 phase and an αFe-αCo phase. The alloy is useful as a valve seat insert for internal combustion engines such as diesel engines.
