V1360 HS{Lord Ernest Hives - Chair}5/LG3.11.27. NON-CORROSIVE TREATMENT. V1360 The aeroplane builders, especially Faireys, are much more advanced than we are on the use of non-corrosive treatment of materials. It is not that we do not have trouble from corroding, because we are in constant trouble with engine parts corroding and rusting even whilst the engines are on test. Also on the motorcar pieces there is plenty of scope for eliminating rust. For steel, Fairey is using Cadmium plating; from the samples we saw, which had been sprayed with sea-water for weeks, it is remarkably effective. For aluminium and duralumin, they use the annodic treatment. We are certain that we shall have to come to this, we are already in serious trouble with corrosion of the aluminium on Condor carb. throttles. Hl. has experimented with Cadmium plating and has samples nearly two years old which are in excellent condition. We are arranging for him to treat a set of those parts we usually find rusty on a F.ll. We have no suitable plant for annodic treatment and therefore propose to send such pieces as carb. parts, water pump etc. to Faireys. HS.{Lord Ernest Hives - Chair} | ||
