Tribochromism
From Wikipedia, the free encyclopedia
Tribochromism refers to a change in colour of a material caused by mechanical friction. In many areas of work which involve machinery there is friction between the mechanics. In certain cases the friction caused by machinery requires detection. In these situations the use of tribochromic materials takes place. Just like other substances that come under the chromic name the effects are reversible and the uses of this form of material are plentiful in the field of mechanics/mechanical work. Friction is a force that causes problems with machinery. Quite often when machines are working they tend to ‘rub’ of have ‘friction’. Machines, such as cars, aim to reduce friction by decreasing surface area contact between parts or with the use of a lubricant. Even then, friction may still occur which results in heating. Heating in machinery results in wear- this means that machinery may have to be replaced and does not last as long as it would if friction was not present. Sometimes it is necessary to know when friction is occurring so that measures can be put into place to reduce friction. This is where tribochromic materials come into play- they are used to detect mechanical friction. In fields of work concerning mechanics this smart material would prove indispensable.
