Investigation Of Sample Position Effect On Produced Coating During Mechanical Milling
Tool steel substrate was coated by titanium carbide using mechanical milling technique. Titanium and graphite
powders was used as starting materials with molar ratio of 1:1. During the milling process the effect of substrates position at
milling vial was checked to find the best condition of milling. Phase transformation and structure of the coating at different
stage was analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The measurments of
microhardness was performed on both fixed and mobile substrates. It was noticeable that substrate position influenced
hardness, thickness and structural properties of the coatings.
