Erosion wear resistance and impact-induced phase transformation of titanium alloys TA2 (pure Ti), TC4 (Ti–6Al–4V) and TC11 (Ti–6.5Al–3.5Mo–1.5Zr–0.3Si) were investigated using a slurry jet tester. The slurry erosion wear resistance of TA2 is comparable to that of 304 stainless steel, especially at the impingement angle 90°. …

Erosive Wear | SpringerLink
The mechanisms of erosive wear span a continuum from single-particle impact to the sliding of a compact bed of slurry particles, here referred to as sliding-abrasion wear. The majority of actual slurry erosion processes fall somewhere between, where a dense mixture of solids and fluid interact with the wetted surfaces (and each other) in a …

Erosive Wear
Unlike sliding wear, there is less work on solid particle erosion of nanocomposite coatings. Only work by Dent et al. (2002) indicates that erosion resistance of nanocomposite coating decreases compared to conventional coatings. However, in nanostructure coatings, erosion resistance increases with the decrease in Co binder phase.

What is Erosion Wear
Surface Hardness and Wear Resistance. Hardness is important from an engineering standpoint because resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness. If the hardness of the material is higher than that of the abrasive material, less wear rate will occur.

What is Erosion
Erosion – Corrosion. Erosion can also occur in combination with other forms of degradation, such as corrosion. This is referred to as erosion-corrosion. Erosion corrosion is a material degradation process due to the combined effect of corrosion and wear. Nearly all flowing or turbulent corrosive media can cause erosion corrosion.
