Hi Guys
I need urgent assistance.
We quoted a job for a customer on which they supplied us with limited information.
They required us to blast and aluminuim flame spray steel pipes.
After site setup was done they supplied us with a document containing their requirements. The specification calls for Arc spray, adhesion of 1000 to 2000 psi, surface profile 75-125. The data sheet we have on the aluminuim wire says that flame spray application will achieve
up to 800 psi. How do I go about improving the adhesion of the coating ? Will heating the steel help allot or will a courser profile do the trick ?
Thanks
