Effect of the Deposition Time and Heating Temperature on the Structure of Chromium Silicides Synthesized by Pack Cementation Process

Transition metal silicides have attracted great interest for their potential use in optoelectronic devices, photovoltaic cells, and thermoelectric conversion elements because of high melting point, oxidation resistance, satisfactory properties. This study focuses on the effect deposition time heating temperature morphology structure chromium synthesized by pack cementation method. A series experiments were carried out at various temperatures (1000–1150 °C) with different times (15–120 min). The chemical composition samples determined using SEM an EDS analyzer. determination phase identification performed XRD analysis. examination as-formed materials was completed performing thermal stability tests. most suitable conditions producing CrSi2 sample properties simultaneously minimizing cost production are listed. It found that 1000 °C 15 min during chromizing step, combination siliconizing step 60 min, presents best these selected offer appropriate, economical, repeatable results.
