Development of dense hydroxyapatite-ni by modified electroless deposition technique.
Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin; Azmi, Rahmat, Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2014)Ni deposited on HA powder was prepared by electroless plating process without sensitization and activation treatment. The deposited powder obtained was characterized by energy dispersive spectroscopy (EDX) and x-ray ... -
Effect of different nickel content on the mechanical properties of hydroxyapatite-ni composites from coated powders
Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin; Azmi, Rahmat, Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2014)HA-Ni composites were fabricated by uniaxial pressing from coated powders, in which HA particles were successfully coated with nickel precursor by the electroless deposition method. The compacted powders sintered at ... -
The influence of welding parameters and corrosive environment on the joint strength of resistance spot-welded mild steel sheets
Shamsul Baharin, Jamaludin, Prof. Dr.; Ahmad Latiffi, A. A. T.; Khairel Rafezi, Ahmad; Md. Fazlul, Bari (University of Malaya, 2009)In the present work, mild steel sheets consisting two batches were welded by resistance spot welding at different welding parameters and exposed under different environments. The 5% sodium chloride brine was used in the ... -
Novel of Binary Metal-Non Metal Material for Chair Flower Product (Novel AI - PP for Chair Flower Product)
Mohd Ichwan, Nasution, Prof. Madya Ir.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Khairel Rafezi, Ahmad, Dr.; Chek Idrus, Omar; Mohamed Faisol, Mohamed Nor; Mohamad Safwan, Isa (Universiti Malaysia Perlis, 2009)Material for aluminium product usually made from aliminium scrap. Nowadays, the price of aluminium scrap is increased. The idea is how to minimize the cost of production via minimize the weight of the product without ... -
Preparation and characterization of Co-HA powder using modified electroless method
Mohd Zaheruddin, Kasmuin; Sri Asliza, Md Amin; Azmi, Rahmat, Prof. Madya Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2014)C0-HA composite produced by simple electroless deposition method was studied. From the particle size analysis by Malvern particles analyzer its shows that 19% increment in average of the particle size powder increase after ... -
Sintering effects on mechanical properties of Co-HA composite prepared by modified electroless deposition.
Mohd Zaheruddin, Kasmuin; Sri Asliza, Md Amin; Azmi, Rahmat, Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2014)Co-HA composite produced using electroless deposition without conventional sensitization and activation treatment was studied with varying sintering temperature (1100°C, 1200°C and 1250°C). The particles size, bulk density, ...
