Cladding for abrasion resistance
Cladding for abrasion resistance
(OP)
First, given the choice between inconel and tungsten carbide which would be a better choice for longevity?
Second, any other choices to consider?
Either would be clad to 316SS.

RE: Cladding for abrasion resistance
I assume that you are talking about a flame spray or HVOF type of coating.
One problem with carbide on SS is that you will need a high binder level so that you have some 'give' to the coating since the substrate is so soft. You also need to use a Ni or mixed alloy binder rather than Co for corrosion resistance.
If these are big heavy parts that can be weld overlayed then I would also consider a Stellite type of coating.

RE: Cladding for abrasion resistance
When you say clad, do you mean weld overlay or thermal flame spray? You can clad Inconel plate, but there is no tungsten carbide plate to clad.
You can easily flame spray tungsten carbide over Type 316L sst without a more ductile inner layer.
If you need corrosion resistance and hardness, I recommend you try Ultimet or Tribacor alloys applied via weld overlay.
Bottom line, you need to better define what you need before an good answer can be given.

I think we need more specificity here in order to give a coherent answer.

RE: Cladding for abrasion resistance
now it looks like cladding is out, based on some of your comments and a little side research, and consideration for alternate base material is being considered.
stellite is not a contender for the design. the design is proprietary and am now waiting to see what the design owner comes up with.
this has been a learning experience for me and you guys are great for offering your expertise.
thanks
