mechanical abrasion

Typically these processes involve surface etching, flame treatment or mechanical abrasion.

Mechanical abrasion of the titanium oxide film leads to increased corrosion rates.

The Blu-ray Disc specification requires the testing of resistance to scratches by mechanical abrasion.

The materials used are in general UV resistant and are used for their capacity of chemical stability and mechanical abrasion.

Another non-chemical separation technique utilizes steam heat, mechanical abrasion, and a light vacuum to separate the hard eggshell from the protein-containing membranes.

The Basic health and safety requirements of the directive include the risks or mechanical abrasions and impact and risk to the health and hygiene of the end user.

Bristle blasting, also termed Wire Bristle Impact, is a mechanical abrasion cleaning process that is performed on metallic surfaces by a brush-like rotary power tool.

Another use for selenious acid is the chemical darkening and patination of copper, brass and bronze, producing a rich dark brown color that can be further enhanced with mechanical abrasion.

Metals such as brass are often chosen for bearings, bushings, and other sliding applications because of their resisitance to galling, as well as other forms of mechanical abrasion.

The coating is also robust and cannot be damaged by application of Scotch tape or moderate mechanical abrasion; Pilkington claim that the coating will last the lifetime of the window frame.

In their headlong rush they naturally tend to get their corners knocked off at each bounce, so they end up as peculiarly smooth, rounded lumps, the smoothness being the result of mechanical abrasion.

In general, lianas are detrimental to the trees that support them: growth rates are lower for trees with lianas, they directly damage hosts by mechanical abrasion and strangulation, render hosts more susceptible to ice and wind damage, and increase the probability that the host tree falls.
