The Development and Applications of Powder Metallurgy Manufacturing Methods in Automotive Industry

Abstract

Over the past decade, automotive industry has developed considerably faster than other sectors in direction of consumers' demands. In order to provide worldwide emission standards, focusing on new technologies and enhancing fuel efficiency is emerged as a new trend among automobile manufacturers. Producing more efficient, lighter and eco-friendly cars without compromising performance and comfort has been the main goal of automotive industry in recent years. The high technology requirements of passenger cars with internal combustion engines as well as in hybrid and electric cars have directed the companies in sector to investigate alternative production methods. When compared with conventional manufacturing processes, powder metallurgy (PM) production methods are increasingly preferred by automobile manufacturers as they allow both profitability and part production in some special applications. In this review paper, it is aimed to give information about the development and application of PM methods in automotive sector.

Recent Advances In Production of Automotive Industry’s Spare Parts By Powder Metallurgy

“…Recently, PM methods have determined all the above-mentioned requirements, which will be the most common technique used for manufacturing many automotive parts [4][5]. PM engineering parts are in high international demand in the automotive sector due to their functional flexibility and cost benefits.…”

Microstructural Investigation and Impact Strength of Sinter-Hardened PM Steels: Influence of Ni Content and Tempering Temperature

“…Powder metallurgy (PM) is a promising technology for the cost-effective production of near-net shape components across several engineering industries. PM steels find extensive applications in the automotive field, meeting the demand for complex and multifunctional parts, e.g., engine, transmission, brake, chassis and electromagnetic components [1][2][3][4]. On the industrial scale, PM steels can compete with conventional steels and are broadly employed in gear manufacturing, where wear, fatigue and dynamic resistance are crucial [5].…”

Wear behaviors at different temperatures of ZrO2 reinforced A356 matrix composites produced by mechanical alloying method

“…In engine parts, the camshaft and crankshaft gears, the timing gears, gear type oil pumps, the water pump impellers, the distribution pulleys, the fuel pump parts, the flange distributor gears, swing arm supports and attachments, engine ears, valve weights, valve housing inserts, valve lift guides, stainless steel gas flap attachments, turbochargers and fuel injector parts can also be produced by PM methods. Besides that, in transmission parts, all major components of both semi-automatic and automatic transmissions: hubs, clutch plates, clutch plate bearings, synchromesh parts and many other components have recently been produced by the PM method (Erdem, 2017; Fujiki, 2001). PM method compared with conventional manufacturing methods (machining, casting and forging) has advantages such as low production costs, high tolerance and little need for secondary processing (Torralba et al , 2003), very low interface reactions between matrix and reinforcement (Ay et al , 2016), homogeneous particle distribution (Lim et al , 2003) and low processing temperatures (Ozyurek and Ciftci, 2011; Özyürek et al , 2010).…”
