摘要： The disclosure concerns steel cylinder barrels for piston pumps and motors having bonded non-steel valve plates. The valve plate comprises a sintered iron powder matrix which is impregnated with bronze and is metallurgically and mechanically bonded to one end of the steel cylinder barrel. The valve plate is made from a porous sintered iron blank which is mounted in contact with one end of a steel barrel blank in an assembly which includes a mass of bronze in the solid state. The assembly is heated in a nonoxidizing atmosphere to a temperature between 1900*F and 2000*F to melt the bronze and cause it to infiltrate the sintered valve plate blank and bond to the steel. Thereafter, the assembly is cooled in the non-oxidizing atmosphere to solidify the bronze, followed by air cooling to room temperature. Finally, the finished valve plate is machined from the bronze-impregnated sintered preform.

摘要： The disclosure concerns cylinder barrels for piston pumps and motors which have lined cylinder bores. Each liner comprises a matrix of sintered, powdered iron which is impregnated with bronze, and which is metallurgically and mechanically bonded to the steel barrel. The liners are formed from porous, sintered iron sleeves which are placed in the bores in contact with bronze slugs. The assembly is heated in a non-oxidizing atmosphere to a temperature between 1,900*F and 2,000*F to melt the bronze and cause it to infiltrate the sintered preform and bond to the steel. Thereafter, the assembly is cooled in the non-oxidizing atmosphere to solidify the bronze, followed by air cooling to room temperature. Finally, the finished cylinder bores are machined in the bonded bronze-iron sleeves.
