Purpose: Aim of the study is to improve the bioactivity of CoCr alloy upon covering the surface with titanium based coating. Design/methodology/approach: CoCr alloy was coated by cold spraying of powder mixture having a composition of 92 wt.%Ti + 8 wt.%Al. Coated samples were thermally oxidized at 600°C for 60 hours. Characterization of the coating was made by X-Ray diffraction analyses, microstructural...
Purpose: The technological properties of WC-Co tool materials fabricated by spark plasma sintering has been investigated. Design/methodology/approach: The technological properties has been investigated using instrumented indentation and a Vickers tip indenter with an applied load of 300 mN. SEM and LM methods were used to characterize the microstructure. Findings: The best results of nanohardness...
Purpose: Effect of filter types on filling during low pressure die casting researched to find optimal filtration design for wheel casting process. Design/methodology/approach: Three types of filters, which are commonly used during low pressure die casting for light alloy aluminium wheel production, investigated with numerical simulation. In addition, numerical simulation for without filter is made...
Purpose: To synthesize bioplastics on a small scale from starch available in potato and to study the characteristics of the same when pectin is blended with it. Design/methodology/approach: The bioplastics are fabricated manually using starch extracted from potato and glycerol. Pectin was blended to this combination to synthesize another set of bioplastic films. The characterization of the obtained...
Purpose: High-strength low-alloy (HSLA) steels have been used in a wide range of applications from automotive to ship building industry due to their low weight, formability and good weld ability. However, especially in the automotive industry, it is still attempted to improve this steel for the better formability and strength properties. Grain refinement is a well-known method to improve mechanical...
Purpose: In this study, the join ability of dual-phase automotive steel sheets by metal inert gas brazing method was aimed. DP 600 (Dual Phase) steel plate shaving 1 mm thickness were joined by copper-based (CuAl8) wire in gas metal arc brazing technique. Design/methodology/approach: Specimens were prepared in butt joint form. Brazing operations were done with nine different Brazing arc voltage of...
