Wear is a damage to solid surface that generally involves progressive loss of material and is due to relative motion between that surfaces.

Elemental powders of atomized iron (Fe), graphite (C), and titanium were weighed accurately and homogeneously mixed to compose an alloy powders of Fe-1%C, Fe-1%C-1%Ti, then compacted into cylindrical billets of size (Ø25X33mm) using suitable circular die-punch set in a 100T capacity hydraulic press. The compacted specimens were subjected to sintering and subsequently sintered specimens were once again heated to a temperature 1000°C and hot upsetting was carried out on the heated specimens.

Abstract
Wear is a damage to solid surface that generally involves progressive loss of material and is due to relative motion between that surfaces. The present work aims to study the effects of Titanium (Ti) addition on wear behaviour of Powder Metallurgy (P/M) plain carbon steel. Elemental powders of atomized iron (Fe), graphite (C), and titanium were weighed accurately and homogeneously mixed to compose an alloy powders of Fe-1%C, Fe-1%C-1%Ti, then compacted into cylindrical billets of size (Ø25X33mm) using suitable circular die-punch set in a 100T capacity hydraulic press. The compacted specimens were subjected to sintering and subsequently sintered specimens were once again heated to a temperature 1000°C and hot upsetting was carried out on the heated specimens. Then the machining was performed on hot upset specimens to get wear test specimens of sizeϕ6X50mm. Using design of expert (DOE) software, the sliding wear experiments were planned on pin-on-disc Tribometer. The images of maximum worn out surfaces and microstructures of the alloy steels were captured and compared with wear behaviour of the alloy steels. The results are represented on 3D &2D Surface plot for comparing the response factors of both the alloy steels. It is found that the delamination wear is predominant at higher loads on both the alloy steels. The empirical equations for mass loss and coefficient of friction with respect to load and speed are developed for both the alloy steels.
