Event: ICMCTF 2020 – San Diego, California, USA, 26 April-1 May 2020,

Technical Director, Dr Yuri Zhuk has been selected to present a paper ‘Nanostructured CVD W/WC Coating with Enhanced Resistance to Water Droplet Erosion and Cavitation’ at The International Conference on Metallurgical Coatings and Thin Films (ICMCTF) be held in San Diego, California, USA from 26 April to 1 May 2020.  ICMCTF is recognised as the premier international conference on thin film deposition, characterisation and advanced surface engineering. It provides a forum and networking platform for scientists, engineers, and technologists from academia, government laboratories and industry.

Water Droplet Erosion (WDE) and Cavitation Erosion (CE) are complex phenomena which have significant similarity, so materials resistant to CE often show enhanced resistance to WDE.  WDE damages the leading edges of steam and gas turbine blades, increasing turbine rotation drag and leading to costly maintenance. Cavitation Erosion (CE) damages pump and valve components, flow control and marine equipment. Protection of industrial equipment against WDE and CE is a pressing industry demand and advanced coatings are considered a promising solution. Yuri will present the testing of the Hardide nano-structured CVD WC/W metal matrix composite coating’s resistance to WDE and CE and discuss the key factors affecting its performance.
