INTRODUCTION

Tribology is defined as science and technology of interacting surfaces in relative motion and of related subjects and practices. However the subject Tribology generally deals with the technology of lubrication, friction control and wear prevention of surfaces having relative motion under load.
The two main constituents of Tribology are friction and wear, which controlled and reduced, automatically increases the service life of machine elements.
In past few years, wood iron and skin have been used as journ ....etc

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations
steel polypropylene, steel polyester and steel glass. The flexural properties were studied using four point bending t ....etc

A STUDY ON WEAR AND EROSION PROPERTIES OF RAIL STEEL



Introduction:
Steels represent the most important group of engineering materials as they have the widest diversity of applications of any of the engineering materials. Generally, carbon is the most important element profoundly affecting the mechanical properties of the steels. The term steel is used for many different alloys of iron. These alloys vary both in the way they are made and in the proportions of the materials added ....etc

ABSTRACT

Corrosion, Stress Corrosion Cracking (SCC) and corrosion fatigue failures of high strength aircraft aluminums are costly and potentially catastrophic material problems affecting the aircraft fleet today. As the service lives of aircraft are extended, the increasing inspection and repair of corrosion in aging aircraft adversely affects fleet readiness, the cost of operation, and personnel safety. Shot peening (SP) is a widely used ....etc

PROPERTIES OF GEAR MATERIAL AND THEIR ADVANTAGES



Introduction

In order for gears to achieve their intended performance, life and reliability, the selection of a suitable gear material is very important. High load capacity requires a tough, hard material that is difficult to machine; whereas high precision favors materials that are easy to machine and therefore have lower strength and hardness ratings. Gears are made of variety of materials depending on the requirement of the ....etc
