The effect of sub surface defects in surface roughness monitoring through ultrasonic flaw detector.
Objective
 To study the effect of sub surface defects in surface roughness monitoring through ultrasonic flaw detector.
 To study the sizing of defects.
Ultrasound Concepts
• All sound waves, whether audible or ultrasonic, are mechanical vibrations involving movement of the medium in which they are traveling. A sound wave may be transmitted through any material which behaves in an elastic manner.

magine if killing flu viruses and other microbes were as simple as turning on a light.

Exposing a unique surface coating to light may in fact hold the key to protecting you from virtually all viruses and bacteria, including the feared avian flu.

Laboratory testing of a novel, permanent nano-coating, developed in collaboration by researchers at North Carolina State University College of Textiles and Emory University School of Medicine, has been shown to kill or inactivate most viruses and bacteria when exposed to visible light. Early tes ....etc

ABSTRACT

The concept of insulating cooled heat engine components such as gas turbine blades and diesel engine valves from hot working fluids with a ceramic thermal barrier coating is by no means new. A practical system, however, has only been identified in the past few years. Thermal barrier coating (TBC) are applied to metallic components to reduce metal temperature, reduce life cycle cost, increase the environmental resistance and in some cases reduce noxious exhaust emissions. The selection of TBC involves many consider ....etc

SYNOPSIS
Coating has always been a necessary job for protection of the object (substrate). Coating is a covering that is applied to the surface of an object, usually referred to as the substrate. In many cases coatings are applied to improve surface properties of the substrate, such as appearance, adhesion, wetability, corrosion resistance, wear resistance, and scratch resistance.
This project is directed to a system for making the use of metal powder for the purpose of making coating on substrate for purpose of improving its propertie ....etc

Abstract

Titanium nitride (TiN) is an extremely hard ceramic material, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.


Applied as a thin coating, TiN is used to harden and protect cutting and sliding surfaces, for decorative purposes (due to its gold appearance), and as a non-toxic exterior for medical implants.

TiN coating is for edge retention and corrosion ....etc

ANALYSIS OF CATALYTIC COATING IN THE COMBUSTION CHAMBER IN FOUR STROKE ENGINES

ABSTRACT:


The analysis of catalytic coating in the combustion chamber in four

stroke engine is done in order to improve the performance of the vehicle and also to

reduce the percentage of harmful pollutants in the exhaust gas. In four stroke engines,

the combustion chamber is modified by applying catalytic coating means of

electroplating. Catalytic materials are used in order to provide minimize the pollutant
