Graphite/ Epoxy-Graphite. Electroplating onto graphite plays a role in the construction of materials used in a variety of industries. This process has been in use for decades. During the Victorian era, electroplating was even proposed as a means of embalming corpses, according to an article written in 1890 in The Anaconda Standard.

Modern graphite manufacture commences with a high molecular weight hydrocarbon, often natural pitch or a residue of crude oil distillation, which is first converted to coke by heating in the absence of air. This is long and complex process, usually taking several weeks to perform. The result of the process is that the carbon atoms order ...

The process is called Chemical Vapor Deposition (CVD). The resulting material is ultra pure anisotropic graphite possessing near theoretical density (no pores), excellent thermal conductivity and high strength. Pyrolytic graphite is used as a non-permeable coating on sintered graphite. to top

The unit will introduce learners to a range of techniques and primary processes but will provide a deeper understanding of the more common processes. For each technique and process learners will form an appreciation of the fundamental process requirements, the working techniques used and the relevant health and safety considerations.
