A pulsed Nd YAG laser beam has been used at 532 and 1064 nm to irradiate graphite-metal composites in many studies.High efficiency laser-vaporization methods such as ultrafast pulses from a free electron laser and... 

Graphite coated metal nano-clusters are synthesized using electric arc techniques. The metal of interest and carbon are co-evaporated by an electric arc between a tungsten cathode and a graphite/metal composite anode. An encapsulation occurs in-situ. 

Figure 11 Evaporation chamber used by Maser and his co-workers. The laser beam (A) is guided into the evaporation chamber and focused onto the graphite-metal composite target rod (B). Inert gas is introduced through a nozzle (C). Products are collected on the Cu wire system inside the quartz tube (D), leading to the filter and pumping unit. Adapted with permission from Maser, W.

Graphite lubricants include the dry powder, admixtures with liquid lubricants or greases, volatile liquids compounded with film-forming substances to produce bonded dry films, synthetic resins and powder metal compositions containing graphite for bearings, and finely divided suspensions in liquids (colloidal graphite). 

Scaling results for the flake graphite cast irons a, b, d and e in Fig. 7.21 show that the weight increase related to surface area due to scaling rises as the quantity of graphite increases with increase in carbon content (iron a), and as the graphite becomes more widely dispersed in the matrix (iron d). Apart from carbon content, changes in the base metal composition and...

It is interesting to note that the development of plate materials from graphite to composite to metal is a process from application of the expansive pure graphite to less graphite in composites until no graphite is contained in the metals. In a certain sense, the development process may suggest cost reduction as a dominant factor in the development of plate materials and plates when the other requirements are maintained.
