As there are a lot of works that are published over the years that compare the mechanical properties to abrasive wear behaviour. According to Lancaster model, the UTS, elongation (total) and hardness considered alone are can be sometimes related to abrasive wear behaviour. However, the combination of afore-mentioned mechanical properties can be related. similar study was conducted by Ratner et al. where they relate the stress and strain at rupture to abrasive wear that is in good agreement. On what basis we relate the mechanical properties with tribological properties.

The things are that there is no direct correlation between mechnical strength and wear resistance . The rationale here is that sliding friction modifies the subsurface layer both structurally and chemically so that the resulting surface acquires its characteristcs other than those inherent with the base material. Another reason is that for ductile materials wear resistance may correlate with their hardness only when there is no adhesion wear (galling) which is typical only with lubricated testing. For hard materials, the main wear mechanism is subsurface fracture and the more brittle is the material the higher is the risk of fracturing. So each material is between adhesion Scylla and brittle fracture Charybdiss
Thanks for the response, Sergei Tarasov. However, there are many literature by Jayshree Bijwe, A. p. Harsha US Tewari worked on co relating the mechanical properties to abrasive wear.
I agree that there is a lot of literature sources relating abrasive wear and mechanical properties. I also participated in doing research in this field on depositing wear-resistant coatings. The main outcome of my research is that the matrix ductility is necessary to retain carbides from being pulled out during wear. For example retained austenite works so with respect to carbides while hard martensite zones are worn heavilly due to fracture and low ability to retain carbides
Sergei Tarasov, is it generalised for all the matrix material or this phenomenon is only restricted to metal matrix
I think abrasive wear (both two and three body) and sliding wear must be looked at differently. I am not sure that Hemanth and Sergei are talking about the same tribosystem.
Luiz Alberto Pereira das Neves Franco, thanks for the doubt. My question is related to the polymer composites. There are a papers available that relate the mechanical properties for the abrasive wear mechanism. what will be the basis for comparing the abrasive wear to the mechanical properties. However, hardness alone can be related to the abrasive wear mechanism.
