DIAMOND CUTTING TOOL AND COATINGS



Diamond is the hardest material known to man kind. When used on tools, diamond grinds away material on micro (Nano) level. Diamond is the hardest substance known and is given a value of 10 in the Mohs hardness scale, devised by the German mineralogist Friedrich Mohs to indicate relative hardness of substances on a rating scale from 1 to 10. Its hardness varies in every diamond with the crystallographic direction. Moreover, hardness on the same face or surface varies with the direction of the cut.

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

Thermal Barrier Coatings

Heat engines are based on considering various factors such as durability, performance and efficiency with the objective of minimizing the life cycle cost. For example, the turbine inlet temperature of a gas turbine having advanced air cooling and improved component materials is about 1500oC. Metallic coatings were introduced to sustain these high temperatures. The trend for the most efficient gas turbines is to exploit more recent advances in material and cooling technology ....etc

Landscaping
It is an art which deals with conscious arrangement or
organization of outdoor space for human satisfaction and
enjoyment.
Some of its major goals include :-
Organizing and developing the site for maximum use and pleasure.
Creating a visual relationship between the house and the site.
Reducing landscape maintenance to a practical level.
Dealing with health and stress management, energy conservation,
noise
control, erosion control, pollution control.Page 3
