Surface texture is one of the most important topics in today's world of design, development and performance. As tolerances are shrinking and performance demands are increasing, surface texture is rapidly becoming one of the most important aspects of engine and vehicle performance. Every moving component on a vehicle or engine is influenced by surface texture in one or more of the following ways: vibration, sealing, adhesion, traction, emissions, safety, durability, wear/failure analysis. Many of the industry's top warranty issues (leaks, noise, vibration, etc.) are a direct result of surface texture implications.

There is a potential for metal fatigue in any situation where a component is subjected to cyclic loads. Fatigue failures of various types are a key concern in increasing the reliability of products. Problems involving fatigue have become more severe with the demand for lighter weight structures and components. The effective use of fatigue analysis and predictive tools is critical for reducing the development time of new products. Two methods of metal fatigue analysis will be covered. The first is the stress-life approach. This method is used for high cycle or very long life fatigue problems where loads have fairly constant amplitude.

Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures. In addition, key manufacturing areas including stamping and welding will be addressed to demonstrate the increased challenges as compared to lower strength steel grades.

The deposition of thick, pore-free and high performances copper alloy matrix composite coatings is a topic of interest for several industrial applications such as friction materials, high mechanical resistance electrical contacts, and welding electrodes. This study investigates the opportunity to use cold spray for the deposition of CuCrZr/Al2O3 cermet coatings on 6060 aluminium alloys. The project’s aim is to investigate the feasibility of producing integral coolers on mechanical parts. This will make it possible to the design of high performance hybrid motorcycles more compact. Fused and crushed alumina and gas-atomized CuCrZr powder blends have been used as initial feedstocks, with compositional weight ratio of 65/35 and 80/20 (ceramic/metal). The deposition process and coating growth have been studied as a function of carrier gas temperature, exploring the range between 200°C and 750°C. Pure CuCrZr alloy coatings have been also deposited for comparison. The coatings have been characterized in terms of microstructure and morphology, coating microindentation hardness, adhesion to the Al alloy substrate, and cohesion.

Southeast Asian Nations are large scale markets for motorcycles and the market size is still growing. Moreover, the volume of plastic parts used for those motorcycles is increasing with growing popularity of scooter-type motorcycles. Accordingly, decorative features applied for plastic coverings are increasingly important to enhance the attractiveness of exterior designs of those motorcycles. Under these circumstances, we had adopted the magnetically-formed decorative painting and applied to a mass-production motorcycle model sold in Thailand in 2008. The magnetically-formed decorative painting is the method in which the designed patterns are formed by painting the material that contains flakes movable along with the magnetic lines of force, while applying an auxiliary attachment to the backside of the parts for generating magnetic fields, such as magnetic sheet trimmed to fit the shape of ornamenting designs. The magnetically-formed decorative painting offers three-dimensional appearance even though its actual surface has no protuberances or dents.

Recent research has focused on the application of discontinuous carbon fiber/epoxy forging systems to the fabrication of heavy truck cab design. Heavy truck cab designs typically employ sheet metal construction methods but some designs have also employed SMC design approaches. The use of discontinuous carbon fiber/epoxy forging has been utilized to reduce fabrication times and parts integration dramatically. It has been shown that through the use of discontinuous carbon fiber/epoxy forging significantly different design approaches can be implemented and that these approaches are then able to provide substantially improved bending and compressive strength capabilities when compared with traditional sheet metal fabrication design techniques. Here we first describe the background to heavy truck cab design as well as recent developments in discontinuous carbon fiber forging of large structures. Examples of applications are provided. Typical results have been shown to reduce parts integration, lower weight, and reduce final product costs.

There is a significant interest in improving the break thermal efficiency in the next generation diesel engines in combination with reduced weight to achieve improved freight efficiency. Increased exhaust gas temperatures are anticipated in these next generation high efficiency diesel engines. Traditionally, cast irons such as high Si-Mo cast iron have been used in exhaust manifold applications. However the strength, oxidation resistance, and creep resistance of cast iron may not be adequate for operation at the projected higher temperatures. Furthermore, the increased need to reduce vehicle weight necessitates the use of materials with improved high temperature capability but without any added cost or weight. Thus, new materials are needed for use in exhaust manifolds. An alternative to cast irons are cast, austenitic stainless steels that are protected by the formation of a chromia-scale. Although the creep properties of these alloys are excellent, they are weaker than cast irons at room temperatures.
