| Résumé : |
Thermal metal spraying (TMS) has been around and used extensively for protection of a range of steel structures and components, both large and small for very many years (over 65 in my own experience). My first personal experiences of TMS, both sealed and over painted with various paint systems, goes back to the 1960s when I became the first qualified Paint Technologist to join the British Iron and Steel Research Association (BISRA) and joined a team in the corrosion section of metallurgists, corrosion engineers and chemists.
One of my projects was to research the performance of TMS for my then Manager - john Stanners who together with his colleague Ken Chandler (who ran the Corrosion Advice Bureau at BISRA) were to give a paper to the European Corrosion Conference in the Hague. This project involved examining the test panels at all of the BISRA exposure sites in marine, industrial and rural exposure atmospheres and to report on the performance of the various systems under test, some of which had been exposed for over 10 years at that time.
As part of the exercise to establish the practical performance of TMS coatings, I also visited the workshop of the Great Ouse River Board (GORB) at Kings Lynn together with John Stanners. I then learnt that the GORB had setup its own TMS spray shop for the sluice and floodgate corrosion protection in the GORB area, as long as 1948. The work shop manager showed us four sluice gates around the Kings Lynn area and, although these had been immersed in fenland water and one with a marine salt water environment, the structures had lasted for between 15 and 18 years. |
