Ivor Jenkins Medal presented to Dr John Dunkley The UK’s Institute of Materials, Minerals and Mining (IOM3) has presented its 2016 Ivor Jenkins Medal to Dr John Dunkley CEng, FIMMM, Chairman of Atomising Systems Limited, UK. The prestigious award is presented to individuals in recognition of a significant contribution that has enhanced the scientific, industrial or technological understanding of materials processing or component production using Powder Metallurgy and particulate materials.

Dr Dunkley has over 40 year’s experience in atomising plant technology, dating back to his early career when he started the Davy-McKee operation that supplied and installed such plant in 1974. When Davy-McKee decided to withdraw from this business in 1992 he founded his own company, Atomising Systems Limited (ASL).

ASL has now built and supplied around 140 plants to customers in 34 countries. These range from major powder suppliers, of whom around half have dealt with ASL, to small in-house operations.

The company has developed many specialist powders, including water atomised stainless steel powders for filter applications, gas atomised Ag-28Cu powder for brazing and Gas atomised special Cu alloys for diamond tool manufacture. Significant atomisation technology developments made have included technology for the production of satellite-free powders in gas atomisation, ultrasonic vibratory atomisation used for very narrow size range, perfectly spherical solder powder production for electronics and centrifugal (spinning cup) atomisation – which is also used in the latest electronic solder powder plants.

Dr Dunkley also served for several years as Chair of the IOM3 Particulate Engineering Committee.
