This note is for anyone interested in repairing aluminium castings or who want to protect steel work from corrosion. Over the last 10 years or so, the use of cold fusion spaying of metal has come of age. Originally developed in Russia and the middle east the process involves blasting a dust of your chosen metal at high speed at the metal you want to repair. The speed used makes the metal dust weld to the base metal. When I first looked at this process 5 years ago it was expensive and still considered "suspect". It has since come down in price and become very main stream. My contact in Lithuania is now offering a machine for 6000 euros and the consumables are around 50 euro per Kg.
The reason is it so interesting is that it does not raise the temperature of the casting or metal you are repairing. Perfect for working on aluminum castings that you don't want to warp. Once you have built up the area of damage, you can machine it back to final dimensions. The MG car club now have a machine and Honeywell use the process to repair jet engine components. It can also be used to fuse zinc to steel without using bulk heat, brilliant to corrosion protect panels and chassis. I believe I say the process being used to protect London underground iron tunnel hoops. (bbc documentary). I attach a picture of the machine and the specification sheet for the consumables. I will be on the Jowett stand at the restoration show in March 19 if you want to hear more.
If this sounds interesting, lets keep talking and see if it is worth learning more.
