3/16" wire metal spraying
Dear All;

Could you please share your experience about using 3/16" (4,76 mm) arc-wire system compared to 1/8" (2,3 mm) arc sytem?

Regards

Hi diraztol

Welcome to the Surface Engineering Forum.

I have no experience with the 3/16 arc wire coatings. I'm led to believe that relative coating quality is not an issue. Generally, wire size goes up with power and spray rate. I think 3/16 arc wire would only be advantages when spraying zinc and aluminium coatings at very high spray rates with power levels around 500A and upwards.

Mr. Gordon;

Thanks for the response. You are quite right that we do use current levels above 500 A with 3/16" Aluminium wire. The service engineer from Metallisation have claimed that generally you do get finer(less porous) coatings with small diameter wire? Is that correct?

Regards

Hi Diraztol

I would expect to be able to produce finer coatings using smaller diameter wire, but this is also very dependent on the equipment design and parameters selected (atomising gas pressure/flow, air caps etc.).

Hi Diraztol,

How often do you spray zinc or aluminum wire?

Danns;

We are both using pure aluminium and pure zinc at our paintshop from time to time. But zinc is more oftenly used since we are asked to metallize the flanges of windtowers in paralel with our customers anti-corrosion specifications.TSA is less frequent at our job. (say 6 months between applications.)

hi, I used Metallisation machine before. The model is Thermion. Try not to use current above 500A for long term or else the trisitor (US$1000+ per piece) inside the Miller will damage easily.

P/S: How come suddenly got 2000+ people view this thread?

Powerman,

You said that you use both aluminum wire and zinc wire for metallisation.

What is the name of your company?

Thanks

One (maybe) useless comment. With this size of wire you easily get a splattered particle size due to wire straightness and nozzle orientation.
