Explain In detail all tribological phenomenon parameters Inv

Explain In detail all tribological phenomenon, parameters. Involved between similar and dissimilar non-metals. Illustrate your response with examples. I raised this question for discussion in class room. Dissimilar non-metals is understandable. Weaker one wears the most, but what happens If the contacting surfaces are similar? Material distortion is one reason. No material is lost but distortion will cause the seals to lick, etc. Develop the answer as best as you can based upon your research In tribology. I am looking for in-depth responses. Do not use long sentences. Use bullet points. Exhaustive list will be appreciated.

Solution

1)A science that deals with friction,lubrication and wear in all contacting pairs.

2)Although the wear and friction of non metallic solids have some fundamental similarities to that of metals but there are also significant differences.

3)These differences can be exploited to produce valuable new bearing materials which can change commonly expected expectations of tribological performance.

4)For eg-PTFE is soft and has a very high wear rate so that for most applications it must be blended carefully with other materials before a useful bearing material is created.

5)A through study of the tribology of non metallic material is a prerequisite to their succesful adaptation as bearing or wear resistant material.
