Failure Analysis and Remanufacturing of Construction Machinery Shafts by HVOF Technique MA Ning1,2,a, WU Huantao1,2, YE Fuxing1,2,b and ZHANG Guosheng3 1School of Materials Science & Engineering, Tianjin University, Tianjin 300072, China 2Tianjin Key Laboratory of Advanced Joining Technology, Tianjin 300072, China 3Tianjin Research Institute of Construction Machinery, Tianjin, 300384, China alsxzmn@163.com, byefx@tju.edu.cn Keywords: remanufacturing, cross shaft, HVOF, WC-12Co Abstract.
Materials Samples for failure analysis were taken from the local position of the shaft which was assembled at differential of ZL50C loader.
Agglomerated WC-12Co powders with submicron structure produced by Ganzhou Zhangyuan Tungsten New Materials Co., Ltd, China were used for the present study.
It can be seen from Fig. 3 (a) that the four journals were worn due to the friction with planet gears in service.

Introduction The 7xxx series aluminum alloys have been widely used as structural materials due to their attractive comprehensive properties, such as low density, high strength, ductility, toughness and resistance to fatigue [1-3].
It means that the experimental material is a sensitive material of positive temperatures of 32℃, 400℃ and 480℃.

In addition, there are two constitutive relations which describe how fields interact with materials: D t= εt* E (t) (5) B t= μt* H (t) (6) Where εt is permittivity in F/m and μt is permeability in H/m.
The refraction index of a material is used to make a meaningful description which can be calculated as: η= μrεr (7) The magnetic response in most of materials is negligible (μr=1); hence, the refraction index can be simply estimated as η= εr.

Introduction Owing to its high anti-corrosiveness and outstanding resistance to fatigue, CFRP (Carbon Fiber Reinforced Polymer) is today the subject of studies for its use not only as material for the repair and strengthening of degraded structures but also as a material replacing steel reinforcement and tendon.
However, the CFRP member is featured by a low lateral stiffness, which necessitates special anchorage when assessing its material properties or using it as tendon.
However, the ACI [1] recommends to limit the maximum tensile stress of CFRP to 60% of its tensile strength considering the uncertainty related to the FRP material.
Fabrication of Specimens The bond type anchor specimens for the evaluation of the material properties were fabricated in compliance with the method proposed in CSA S806-02 [2].
