The Role of Ultrasonic Surface Treatment on Mechanical Properties of 50%Ni 50%Ti

Abstract To achieve thermoplastics-based composites with high tribological performances, molybdenum disulfide (MoS2) and graphite (Gr) were incorporated separately to a polyamide 66 (PA66) matrix. Two different development methodologies of composites were used. The morphological features and the micro-mechanical properties of composites were investigated to stress the influence of the filler surface treatment and its dispersion. The friction coefficient was evaluated using a ball on a flat micro-tribometer. The wear mechanisms were also characterized. The best tribological performance was exhibited by 10 wt% of graphite. The surface treatment of the filler inclusions by 3-aminopropyltriethoxysilane (AMPTES) showed an improvement in the morphological aspects of adhesion at the filler/matrix interface.

Ultrasonic Surface Treatment

Research based on ultrasonic surface treatment (UST) shows that the operation is beneficial to tribological properties and fatigue life of mechanical structures by enhancing the surface mechanical properties, such as roughness and residual stress, through changing nanostructure induced by severe plastic deformations on the surface. The amplitude of the vibration at the processing end is essential for the treatment effect. This paper presents a way to design an UST device that can control the amplitude and vibration mode.

Kaiser Aluminum

Abstract Kaiser Aluminum alloy KA62 (Tennalum alloy KA62) is a lead-free alternative to 6262. It offers good machinability and corrosion resistance and displays good acceptance of coatings (anodize response). It can be used in place of 6262 because its physical and mechanical properties are equivalent to those of 6262 (see Alloy Digest Al-361, September 1999). This datasheet provides information on composition, physical properties, hardness, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and surface treatment. Filing Code: AL-362.
