In general, again general, Inconel (you don't state which one the 2 dozen Inconel alloys) has poor pure abrasion resistance when compared to tungsten carbide, which is true hard surface. Inconel 725 can be heat treated to fairly high hardness and give both corrosion and good, but not great, wear 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.
