Abstract In this present study, the tribological performance of High Carbon Steel blades of Hand Hacksaw is analyzed through the calculation of abrasive wear at different loads in the High Carbon Steel blades of Hand Hacksaw. The Wear and change in Height of Teeth is calculated for the number of blades of High Carbon Steel at different Loads i.e. 5N,10N,15N and 20N with the help of the experimental Setup prepared. The wear and change in height of teeth of blades is calculated through Mass Loss and Profile Projector respectively before and after cutting the given specimen of Mild steel. Similarly, the wear and change in height of teeth of blades is calculated for similar samples of blades using the lubricant 20W40. The result indicates that the wear in the blades increases with the increase in load and decrement in height of the teeth also increases with increase in Load. On comparison of results obtained from dry condition and wet condition, it can be concluded that while using lubricant the wear reduces in blades and there is less reduction in height of teeth of blades, thus blade life increases.

I. INTRODUCTION Abrasive wear occurs when a hard rough surface slides across a softer surface [1]. ASTM International (formerly American Society for Testing and Materials) defines it as the loss of material due to hard particles or hard protuberances that are forced against and move along a solid surface. Standard Terminology Relating to Wear 1987 [9]. Abrasive wear is commonly classified according to the type of contact and the contact environment. The type of contact determines the mode of abrasive wear. The two modes of abrasive wear are known as two-body and three-body abrasive wear. Two-body wear occurs when the grits or hard particles remove material from the opposite surface. The common analogy is that of material being removed or displaced by a cutting or plowing operation. Three-body wear occurs when the particles are not constrained, and are free to roll and slide down a surface. The contact environment determines whether the wear is classified as open or closed. An open contact environment occurs when the surfaces are sufficiently displaced to be independent of one another ASM Handbook Committee 2002 [10].
