Sažetak
Nitrocarburizing is one of the frequently applied processes that significantly improve the service life of steel parts in the complex activity of mechanical loads, wear, and corrosion damages. Characterization and confirmation of the quality of a nitrided/nitrocarburized layer is a prescribed norm which includes the determination of surface hardness, nitriding hardening depth, compound zone thickness and its porosity. In the testing of surface hardness, in spite of determined conditions, there are additional factors that can affect the obtained result and can lead to a misunderstanding between the customer and the provider of the service of nitriding. In this paper, possible influential factors related to the surface hardness are considered and statistically analyzed by the ANOVA two factor test. The considered influential factors are: surface preparation method and loading force. Tests carried out during the research indicated a significant influence of the loading force and of the surface preparation on the results of the nitrided/nitrocarburized steel surface hardness. Also, the indentation size effect is confirmed in the hardness tests with a small loading force.
