Abstract:
PCT No. PCT/US83/02035 Sec. 371 Date Dec. 27, 1983 Sec. 102(e) Date Dec. 27, 1983 PCT Filed Dec. 27, 1983 PCT Pub. No. WO85/02804 PCT Pub. Date Jul. 4, 1985.A composite piston structure and a method of making same is disclosed. A piston member, carrier member, and ceramic facing member are formed, the piston member being comprised of a material selected from plastic and metal having a density of less than 0.15 lb/in3, the ceramic facing member, preferably comprised of a material selected from zirconia and aluminia, and carrier member preferably comprised of a material selected from stainless steel and cast iron. The carrier member material has a coefficient of thermal expansion differing from the coefficient of thermal expansion of the ceramic by up to 2.0x10-6 in/in/ DEG F. An annular grooved wall is defined in the side surface of the piston member and disposed at a location radially opposite a portion of the carrier member when the latter is wrapped about the top of the piston member. A high energy beam is directed across a zone of the carrier member that is radially aligned with the grooved wall and deployed to melt a portion of the carrier member intersected by the beam, causing the melted material to flow into the grooved wall to fill same and lock the piston member to the carrier member, upon solidification, for conjoint movement.
