When It is a problem that affects nearly all of the older (700,000+ miles) trucks on the road today. It is caused an unusual wear process called "fretting" which causes wear You can fret dress your guitar as often as you need to. One tell-tale sign that it's time is extreme buzzing or dead notes when you play. Several different factors are affecting fretting wear, viz. contact pressure, temperature, amplitude of motion, frequency, number of cycles, surface hardness, friction Furthermore, the long durability of the products, and the need for periodic maintenance and changes of parts also mean that customers often pay a lot of 1.1 This test method evaluates the fretting wear protection provided by lubricating greases.1.2 The values stated in SI units are to be regarded as the standard.

2016-10-04 Fretting wear is one of the most common accelerated surface damages that occurs at the interface of contacting materials which are subjected to small oscillatory movement [1,2,3].Hence, fretting is a widespread problem of practical importance that affects a wide range of electrical equipment, press fits, riveted and bolted joints, leaf springs, heat exchangers, and even nuclear fuel elements. Fretting wear is a small-amplitude oscillatory motion, usually tangential, between two solid surfaces in contact (Peterson, 1980). When this kind of wear is associated with oxidation or corrosion, the phenomenon evolves in fretting corrosion. Fretting wear is the mechanism presently attributed to the wear of femoral stems in vivo. The term fretting denotes a small oscillatory movement between two solid contacting surfaces [ 8 ].
