TribTech provides chemical-mechanical technology that improves physical coupling (friction grip, electrical and thermal conduction etc) between contacting metal surfaces. Other uses include applying treatments to non-metal surfaces such as skin or plastics.   

Trib-Couplings are friction enhanced metal-to-metal couplings such as press-fits, shrink-fits, swaged fasteners etc. Smooth parallel couplings can be used as low cost releasable alternatives to traditional keyways or splines; follow links below for more details.

Trib-Couplings employ a thin film of chemical cold-weld agent placed between pressed together surfaces, the agent enlarges microscopic asperity welds that develop between deforming asperities. This provides instant extra grip without heat or cure. Upon relaxing the contact pressure the welds spontaneously break, without leaving visible damage to the surfaces, hence these enhanced strength couplings can be released and re-made

Recent developments include improvements in thermal couplings, for example in high power density electrical machines steel stators may be a press-fit into the aluminium machine casing that also acts as a heat sink. Upon warming the aluminium casing expands more than steel, thereby reduceing contact pressure, torsional coupling and cooling rate. By incorporating trib-coupled layers of dissimilar materials within the casing it is possible to reverse the unfavourable differential thermal expansion.

Non engineering uses for chemical-mechanical (tribological) treatments.

These chemical-mechanical processes use applicators originally designed to apply chemicals to metal surfaces. In essence they are mildly abrasive tools that  grip and moves the skin to and fro skin over underlying subcutaneous facial tissues which exercises the tissues while applying topical skin care formulations:  

  • Male face-shaving:  novel shave brush that improves wetting, extends razor life, gives closer shave and massages lower face to make it look younger 
  • Cellulite treatment: a body brush with novel stick/slip action that vibrates and massages affected tissues which disrupts adipose fats and reduces cellulite
  • Self-tanning:  applicator exfoliates skin when applying self-tanning lotion while keeping hands clean and dry
