Development of Lining Process for Sliding Element of Hydrolic Machine by "Vacuum Melting and Diffusion" Method.

Lining of hydraulic cylinder made of cast iron with copper alloy

“…These methods are used to line sliding surfaces of hydraulic iron cylinders with copper alloy [2]. One method for lining the inner surface of an iron cylinder with copper alloy is to pour molten copper alloy into a hole in the heated cylinder.…”

“…Although it is generally difficult to obtain junction between iron and copper alloy, methods to do so by the self-welding of copper alloy have been devised by several researchers [1,2]. These methods are used to line sliding surfaces of hydraulic iron cylinders with copper alloy [2].…”

Lining of cast iron cylinder with copper alloy utilising high temperature oxidation

“…[1][2][3][4][5][6][7] These methods are utilised, for example, to line the sliding surface of a hydraulic iron cylinder with a copper alloy. 4,7 One method for lining the inner surface of an iron cylinder with a copper alloy is to inject a molten copper alloy into a preheated cylinder filled with molten borax anhydride. This process replaces the molten borax anhydride with the molten copper alloy.…”

Lining of Cast Iron Cylinder with Copper Alloy

“…Although it is generally difficult to obtain junction between steel and copper alloy, methods to do so have been devised by several researchers. These methods are used, for example, to line the sliding surface of hydraulic steel cylinders with copper alloy [1][2][3][4]. One method for lining the inner wall of a steel cylinder with copper alloy is to pour molten copper alloy into the cylinder that has been previously heated with molten borax anhydride filled in the cylinder.…”
