RE: amorphous non-skid coating
Hi hustzc
to the Surface Engineering Forum.
I will point you in the direction of this thread on similar subject:

RE: amorphous non-skid coating
Hi, Hustzc,
I have experience for amorphous materials.
Genaerally amorphous metal has low friction coefficient and high anti-corrosion properties.
If you want to use to non-skid application, should consider the low friction coefficient such as mixing with abrasive particles.
Liquidmetal technologies' Armacor M information is useful to you.

Hi hustzc

Click on members username and you should be able to contact them via email or private message.
Quote:The non-skid coating should need COF>0.6 ,generally,Fe based BMG have high COF duo to its brittleness but Zr-based BMG
have low COF.Is that right?
So do you mean the abrasive particles should have low friction coefficient ? why?
and what abrasive particles would be better for non-skid application? such as Al2O3 or Carbide or Nitride? any suggestion??
Sorry, talk of COF and BMG's ? is going a bit over my head maybe I'm in need of some strong coffee.
What is the actual application? What is the material and environment that the anti-skid coating is going to work against? COF is pretty meaningless without knowledge of entire system. Surface texture will be of prime importance to anti-skid. Addition of hard particles may make the coating more resistant to wear and retain surface texture for longer, but may have little significant effect on initial surface texture and gripping properties.

RE: amorphous non-skid coating
Hi hustzc
I think arc spray is the more suited process for this coating application, due to low cost, ease of application and importantly its ability to give a wide range of coating textures, which I don't think can be match by the other process at the coarse end.
Coating wise I would strongly consider aluminium, for its anti-corrosion properties, low cost, good texture. Only downfall is wear resistance. Areas of heavy traffic may be worn smooth and require periodic maintenance. The heavy traffic areas could also have additional gritty polymer coatings applied on top. There was a MMC (metal matrix composite) aluminium wire product containing alumina, which was idea for this application, but I believe it is hard to come by now.
HVOF I think is probably not the best suited process here, due to relatively high cost, not so portable, not so easy to use, very smooth coatings.
Coating wise amorphous metal (not sure why this appears to be a strong candidate) and other coatings which are cathodic to the substrate (while possibly being in themselves more corrosion resistance and harder wearing) will not provide the same level of anti-corrosion protection as aluminium unless total environmental exclusion of substrate can be assured.
