I was working on NASA and DARPA star war projects in late
eighties.  Main research was net shape high temperature materials
Would grow SiC,  BN, diamonds and diamond like carbon and
carbon metalics.  The purpose was to grow these materials on desired 
shape graphite mandrels for spaced base weapons to avoid machining.
Feasible to grow a piston, or use these materials as coatings.
A pure SiC piston would take 3-4 weeks of growth using H2 gas
and methyltrichloridesilane at 20 Torr and 1400 C.
