Mechanical properties of carbon nitride coatings by nanoindentation technique

Bachelor Thesis from the year 2018 in the subject Engineering - Mechanical Engineering, grade: 10/10, Panjab University (CSIR-National Physical Laboratory), course: Mechanical Engineering, language: English, abstract: Carbon Steel Rings Used in the textile industries lack the robust qualities required and thus a suitable coating was required to enhance their mechanical properties. The Properties of carbon Steel (uncoated) and coated with carbon nitride were studied using Nanoindentation. Furthermore for the coated samples uncertainty in Nanoindentation was evaluated and taken into account.

This training report gives a brief introduction to Nanoindentation and its wide range of applications along with uncertainty analysis of mechanical properties that might be present during the Nanoindentation process. The uncertainty analysis also shows that Nanoindentation is an effective technique in determining the mechanical properties of carbon nitride coated samples. Not only does the carbon nitride coating improve mechanical properties like hardness and reduced modulus but also adds aesthetic features as well to the carbon steel sample.
