“…The wear resistance of the alloys increased with increasing nickel content up to 3 wt.% Ni and tended to decrease >3 wt.% Ni. The wear rate of the Al-xNi alloys increased with increasing applied normal load [51]. One of the disadvantages with Al is that it leads to corrosion.…”

“…From the pin on disc wear tests performed under 67 N and with 1250 m sliding distance, it was revealed that the ultrasonic treated and non-treated samples exhibited similar amounts of weight loss [50]. Yamanoglu et al [51] studied the effect of nickel (1-5 wt.%) on microstructure and pin on disc wear behaviour of pure aluminium against steel and alumina counter faces. The dry sliding wear response of the Al-xNi alloys against steel and alumina counter faces was investigated [51].…”

Advanced mechanical and wear properties and applications of composites with bases of light weight metals have led to the need of aluminium (Al) metal matrix composites (MMCs). In today's time aluminium (Al) metal matrix composites (MMCs) are considered the most potential material for structural and functional applications. Composite materials with aluminium matrices are used in defence, aerospace, automotive and aviation, thermal management areas. Beneficial properties with reduced prices have enlarged their applications. To obtain desired physical and mechanical properties like high hardness, high strength, high stiffness, high wear, abrasion and corrosion resistance Al is reinforced with different metallic, non-metallic and ceramic elements. Al MMCs are used to make piston, connecting rod, engine cylinders, disc and drum brakes where wear has a great role in the functioning of these components as excessive wear of the mating components sometimes leads to catastrophic failures. Improvement of mechanical, especially tribological properties of hybrid composites were provided by the use of certain reinforce materials such as SiC, Al 2 O 3 and graphite. Hence the present chapter presents a review on aluminium metal matrix composites (MMCs) reinforced with different particulate, whisker, fibres reinforcements highlighting their effect on physical, mechanical and wear behaviour of Al MMCs.

“…The weight loss of specimens during wear tests was measured by weighing the specimens before and after the wear tests. The wear loss values obtained were used to calculate wear rate according to the following equation: W = M/ρD, where W is wear rate (cm 3 m -1 ), M denotes mass loss (g) and ρ (gcm -3 ) and D (m) are the density and sliding distance respectively [36]. The effect of titanium addition on the wear rate of the materials can be seen in Fig.…”

Powder metallurgical Cu-Ti alloys with different titanium additions produced by hot pressing were characterizied by optical microscopy, scanning electron microscopy, X-ray diffraction analysis, and hardness, wear and bending tests. The addition of titanium to copper caused the formation of different intermetallic layers around the titanium particles. The titanium content of the intermetallics decreased from the center of the particle to the copper matrix. The hardness, wear resistance and bending strength of the materials increased with increasing Ti content, whereas strain in bending test decreased. Worn surface analyses showed that different wear mechanisms were active during the wear tests of specimens with different chemical compositions. Changes in properties of materials with titanium addition were explained by high hardness of different Cu-Ti intermetallic phases.

ÖzetFarklı oranlarda titanyum içeren toz metalurjik malzemeler sıcak presleme yöntemiyle sinterlenerek üretilmiştir. Üretilen malzemelerin yoğunlukları, mikroyapısal özellikleri, sertlikleri ve aşınma dayanımları incelenmiştir. Ayrıca aşınma mekanizmasının belirlenebilmesi için aşınma testi sonrası malzemelerin aşınmış yüzeyleri tarama elektron mikroskobu kullanılarak incelenmiştir. Yapılan incelemeler sonucunda titanyum partikülleri etrafında farklı katmanlardan oluşan intermetalik fazlar oluştuğu belirlenmiştir. Oluşan intermetaliklerin malzemenin sertliğini ve aşınma dayanımını arttırdığı tespit edilmiştir. Ayrıca aşınmış yüzeylerde yapılan incelemeler malzemenin sertliğinin değişmesiyle birlikte aşınma mekanizmasınında değiştiğini ortaya koymuştur.Anahtar Kelimeler-Aşınma, Cu-Ti, Mikroyapı, Sertlik, Sinterleme, Toz Metalurjisi Sintering and Characterization of Powder Metallurgic Cu-Ti Alloys AbstractCopper samples with different titanium contents were produced using hot pressing technique. Densities, microstructures, hardness and wear resistances of the produced specimens were investigated. Also to understand the operating wear mechanisms during wear tests worn surfaces of the speciemens were investigated under scanning electron microscope. Microstructural investigations showed that different intermetallic layers were formed around titanium particles. Formation of these intermetallic phases increased hardness and wear resistance of the material. Worn surface investigations showed that change of hardness also changes the wear mechanisms that cause wear damage during wear tests.
