    The Development and Applications of Powder Metallurgy Manufacturing Methods in Automotive Industry
    (Kırıkkale Üniversitesi, 2017) Erdem, Oğuz
    Over the past decade,automotive industry has developed considerably faster than other sectors indirection of consumers' demands. In order to provide worldwide emission standards,focusing on new technologies and enhancing fuel efficiency is emerged as a newtrend among automobile manufacturers. Producing more efficient, lighter andeco-friendly cars without compromising performance and comfort has been themain goal of automotive industry in recent years. The high technologyrequirements of passenger cars with internal combustion engines as well as inhybrid and electric cars have directed the companies in sector to investigatealternative production methods. When compared with conventional manufacturingprocesses, powder metallurgy (PM) production methods are increasingly preferredby automobile manufacturers as they allow both profitability and partproduction in some special applications. In this review paper, it is aimed togive information about the development and application of PM methods inautomotive sector.

    The Parameters and Application Areas of Solid Medium Cementation
    (Kırıkkale Üniversitesi, 2024) Canbuldu, Arif; Erdem, Oğuz
    The design and manufacturing of machine parts covers many aspects of engineering and science. In addition to static and dynamic design, which is the basis of mechanics, choosing appropriate materials and determining the appropriate surface treatment are criteria generally learned through experience or determined by standards. In today's industry, efforts are being made to obtain more durable and lower-cost steels by replacing more expensive alloy steels with lower-cost steels or by hardening the surfaces of low-carbon steels. Carburization, also known as carburization, is a thermochemical surface hardening process generally applied to low carbon steels. The cementation process basically aims to improve mechanical properties such as surface hardness and wear resistance by providing carbon diffusion from the carbon donor material to the steel surface. The cementation process can be carried out in solid, liquid or gaseous medium. In this study, detailed information is given about the processing physics of solid medium cementation, application areas, variable parameters, carbon donor materials in the method, cementation temperatures and times, activator types and ratios used in the process.
