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 o ....etc

ABSTRACT
Miniaturization is the order of the day. Until recently a decade ago traditionally watch parts were considered to be the micro components one can think off. Recent changes in societyâ„¢s demand have forced us to manufacture variety of micro components used in different fields starting from entertainment electronics to be bio medical implants. Present day manufacturing processes used for miniaturization are the micro electronic fabrication techniques used for Micro Electro Mechanical Systems ....etc

THEORETICAL ANALYSIS FOR STUDYING THE
FRETTING WEAR PROBLEM OF STEAM GENERATOR
TUBES IN A NUCLEAR POWER PLANT
ABSTRACT



Fretting, which is a special type of wear, is defined as small amplitude relative motion along the contacting interface between two materials. The structural integrity of steam generators in nuclear power plants is very much dependent upon the fretting wear characteristics of Inconel 690 U-tubes. In this stu ....etc

INFLUENCE OF WHISKER REINFORCEMENT ON THE ABRASIVE WEAR BEHAVIOR OF
SILICON NITRIDE- AND ALUMINA-BASED COMPOSITES
Abstract
 The abrasive wear of brittle materials is generally modeled as an inverse function of both the bulk hardness and fracture toughness.
 According to these models,an increase in the hardness or fracture toughness of a material will enhance its wear resistance.
 However,less is known about how whisker-reinforcement influences the properties that ....etc

INTRODUCTION
Since the worldâ„¢s resources of material and energy are getting progressively, by necessity, there is growing involvement in studies of wear on a global basis. Wear of sliding components result in reduced mechanical efficiency and an irretrievable loss of material in the form of wear debris. Wear at the interface between moving particles is a normal characteristic of machine operation. The kind and rate of wear depend on the machine type. Lubrication is provided between the moving su ....etc
