1  Mechanical Engineering Proposal Seminar Project title Design of fretting corrosion testing set-up for hip joint implants Student - Ivon Tshinkobo Project supervisor – Dr Reza Oskouei x?pageid=2133

2 Content  Introduction  Project vision and goal  Proposal design  Project detailed  Conclusion

3 Introduction  Arthritis is a disease that affects the joints and surrounding tissues to cause pain, stiffness and inflammation.  The most common is osteoarthritis where the cartilage breaks down and the bones rub together. The joint then loses its shape and alignment.  Materials that are used in hip joint implant including  Titanium alloy, Stainless steel, Co -Cr  There are failure issues reported by clinical side are corrosion products.  Metal Ions as a result of fretting wear  Patients have corrosive product around the joint and Ion in the blood

4 Project vision and Goals  Design of fretting corrosion testing set-up for hip joint Implants  Head neck taper  Investigating corrosion  Testing of head-neck interface of a modular hip implant under physiological conditions  Understanding fretting- induced failures in the patient  Set should include corrosion environment  Using Ringer’s solutions

5 Proposal design  We are planning to design a set up specimen  Specimen of head  Specimen of neck

6 Figure 1 Figure one shows how the Testing can be conducted Set up specimen Haber Luggin Fretting pad Specimen Load Corrosion

7 Project Detailed  Time frame  Find actuators, load cell, return spring, measuring cell  Haber-luggin capillary  Piezo-actuator  Laser nano sensor  Specimen to represent head neck  Writing up  Modification of design if necessary

8

9 Conclusion  The aim of this project is to design and manufacture of a fretting corrosion set-up for hip Implant  Investigating failure in the hip implant  Result of Ions in the blood and find solutions  Patient have corrosion product around the joint  Design modification if necessary
