It was accepted that tribology has been very much discipline areas. It was focused on the materials selection used against wear and friction. It was based on basic principles about tribology. Lesson notes and references will be given to students and theycontains industrial engineering problems in a large area Triboloji Dersinin genel amacı, öğrencilere Triboloji (sürtünme, yağlama ve aşınma) ile ilgili genel ve faydalı temel kavram ve ilkeler öğretmektir. Tribolojinin çok büyük ve çok disiplinli bir alanında olduğu kabul edilmektedir. Triboloji Dersin özellikle sürtünme ve aşınmaya karşı kullanılacak malzeme seçimi üzerine odaklanmıştır. Ders temel ilkeler üzerinde durmakta ve öğrencilere verilecek ders notları ve referanslar geniş bir yelpazede triboloji ile ilgili endüstriyel mühendislik problemlerini incelemektedir. |
