ABRASIVE WEAR OF LUBRICATED CONTACTS.

A foil bearing arrangement has been used to investigate the wear of carbon graphite materials running against 316 stainless steel in the presence of a hydrodynamic film of fluid contaminated with particulate material. As the thickness of the fluid film is reduced so the wear rate of the carbon reaches a maximum value, further reductions in thickness actually producing reduced wear rates. Possible mechanisms and implications of this behaviour are discussed.

Characterisation of technology roadmaps: Purpose and format

A report on characterisation of technology roadmaps, its purpose and formats are presented. A fast-start process is developed to support the initiation of technology roadmapping in firms to address the industrial needs. The purpose of each roadmap is related to a number of planning aims: product, capability, integration, strategic, long-range, programme and process planning. The second set of categories are related to the format of the roadmap, based on observed structure: multiple or single layers, bars, tables, graphs, pictorial forms, flow diagrams and text. It is concluded that technology roadmaps processes a great potential for supporting the development and implementation of business product and technology strategy.
