Di Itenas belumlah diajarkan mengenai pengetahuan Tribology maka penulisan tugas akhir ini bermaksud untuk memberikan sumbangsih guna mempermudah pembaca memahaminya. Tribology is defined as the science and technology of interacting surfaces in relative motion, having its origin in the Greek word tribos meaning rubbing. It is a study of the friction, lubrication, and wear of engineering surfaces with a view to understanding surface interactions in detail and then prescribing improvements in given applications. According to Dr. Salomon, former editor of international journal Wear, " Tribology means a state of mind and an art : the intellectual approach to a flexible cooperation between people of widely differing background It is the art of applying operational analysis to problems of great economic significance, namely : reliability, maintenance and wear of technical equipment, ranging from spacecraft to household appliances. " The work of the tribologist is truly interdisciplinary, embodying physics, chemistry, mechanics, thermodynamics, and materials science, and encompassing a large, complex, and intertwined area of machine design, reliability, cmd performance where relative motion between surfaces is involved. Adapun penjabaran materi ini dituangkan melalui pendekatan tanya-jawab, penjabaran rumus-rumus maupun dengan cara menginterpretasikan grafik yang ada didalam materi, cara ini diharapkan dapat membantu pembaca untuk lebih dapat mengerti dalam waktu yang lebih singkat. Penjabaran dari materi ini dilakukan dengan mengumpulkan materi dari beberapa literatur. Adapun literatur yang digunakan yakni, Principles and Application of Tribology. oleh F. Desmond Moore, Principles of Tribology oleh Halling, Lubrication oleh Arthur Edwin Norton dan Contact Mechanics, oleh K.L.Johnson.
