Preparation and mechanical properties of two nickel base alloy coatings achieved by electrospark depositionPing ZHANG 1) , Lin MA 1,2) , Zhijie LIANG 1) and Junjun ZHAO 1) 1) Technology and Science...="ChDivSummary">Ni398 and Ni818 base alloy coatings were deposited on 1045 steel by electrospark deposition technique (ESD). Forming properties, thickness, microhardness and wear resistance of the coatings were......
to high polarity and long chain of castor oil allowing strong interactions with the lubricated surfaces. Key words: Nitinol 60 alloy; oil lubrication; superlubricity; lubrication films 1 Introduction TiNi...]. Clearly, researches will be required to understand the tribological properties of Nitinol 60 alloy under oil lubrication, especially when Nitinol 60 alloy is used as the bearing materials for high-speed......
and that of copper alloy carefully cleaned, and under the pre-pressed stress of 56.6-84.9MPa, at the welding temperature of 750-800℃ and at initial strain rate of (2.5-7.5)×10-4s-1, the solid state... that the strength of joint is up to that of the base metal, but the welding deformation increases with the temperature increasing. So when the requirement on the strength of joint is high, the pressure......
superplastic forming capability at high temperature [10, 11]. In spite of the numerous requirement for the tubes with superior mechanical properties in the industry, the tube SPD processes have been less... of the applied large strains and high friction force due to the large contact surface between die and tube. Hence, the need for appropriate lubrication in the PTCAP process is felt. The proper lubrication......

Thermomechanical Fatigue Behaviour of a Nickel Base Superalloy梁晋,R.M.Pelloux,谢锡善摘 要:<正> The isothermal low cycle fatigue (LCF)and thermomechanical fatigue (TMF) behaviourof a Ni-base superalloy was investigated. Theresults show that temperature plays an importantrole in both LCF and TMF. The alloy shows thelowest LCF fatigue resistance......
On Mechanism of The Effect of Rare Earth on Wearability of Nickel Base Self-Fluxing Alloy Spray-Welding Layers李慕勤,马臣,邵德春,郭面焕摘 要:<正> The mechansim of the effect of rare earth(RE)on wearability of spray-welding layers has been investi-gated by adding RE in ppm into Nickel base self-fluxing alloy powder.The test results show that the microalloy-ing......
