‘Materials DO Matter’ - Seminar Synopsis

It’s too easy to fall into a perception trap that managing friction demands only lubrication. Materials DO Matter.

34 delegates attended a SAIT afternoon seminar on Wednesday 6 February 2019 where six informative presentations looked far beyond surfaces separated by lubrication.

David Beard and Dave Gamble demonstrated that the mining industry have a massive demand for differing types of materials where friction is an absolute necessity from milling and crushing ores right down to drilling tool efficiencies.

Dominic Smit of Isowall SA presented very detailed research conducted with Wits University into the ‘Simulation of abrasive particle collision during submerged polishing of CVD coated hard-metal turning inserts.’

Friction causes wear and controlling wear is subject to the choice and positioning of material in contact with abrasion – Materials DO Matter!

Dr Amanda Jonker


Material Hardness:

  • Piece of Chalk 1
  • Plaster of Paris 2
  • Fingernail 2.5
  • Gold 2.5-3.0
  • Penny 3.5
  • Iron Nail 4
  • Window Glass 5.5
  • Steel Nail 6.5
  • Ceramic Tile 7
  • Aluminium Oxide 9

Dr Amanda Jonker, Senior Ceramist from Multotec, ably demonstrated it was not only the choice of Al2O3 alumina ceramic material that was critical, but how customised applications could position ceramic surfaces to reduce friction wear rates in specific applications. Who would think of aluminium as a top constituent of hardness?

Thuli Mkhaliphi of Wits University showed that tribology was present and significant in the 1st Industrial Revolution and is with us now, even in the digital age of the 4th Industrial Revolution.

investigated research conducted globally about wind-turbine bearing failure – a subject that has not reached conclusion. The growth of wind power makes this an issue for urgent resolution on a global scale. Tribologists of the world – arise!

Customising a solution-driven, integrated approach to friction is the way forward: Materials play a significant role – and DO Matter.
