Transparent Omniphobic Coatings that are Flexible and Wear Resistant
Omniphobic or anti-smudge surfaces require good mechanical durability to ensure that they are suitable for practical applications. In general, the abrasion resistance of a surface depends on its hardness. However, when a coating is very hard, it is usually brittle and lacks flexibility. New coating …

The Development of a Highly Wear Resistant Aluminum Alloy.
Wear has been a subject of concern to man for many centuries, with man having found many ways and means to overcome the problems encountered due to wear. The use of footwear by people, the shoeing of horses and the use of iron rims on wagon wheels were some of the actions taken by man centuries ago …
