Effect of Counterface Material on Tribological Behavior of AISI 304L Stainless Steel Under Marginally Lubricated Contact

Olofinjana Bolutife^*, Ajayi O. A, Lorenzo-Martin Cinta, Ajayi Ezekiel Oladele Bolarinwa

The properties of surfaces in contact are known to have significant influence on the tribological behavior of any tribosystem in different contact situations. In the present work, the effect of using different ball counterface material on the tribological behavior of AISI 340L stainless steel under marginally lubricated contact was studied. The f...

Zeolite NaY from Kankara Kaolin using Commercial Grade Chemical: Effect of Crystallization Time and Temperature

Ajayi O. A^*, Mamman J., Adefila S. S.

Zeolite Y was synthesized using commercial sodium hydroxide and Kankara kaolin as starting material in the presence of sodium silicate formed from kaolinite clay. Synthesis was done at 90°C, 95°C and 100°C for crystallization time of 12, 18, 24 and 36 hours. Results showed that commercial sodium hydroxide could be used to successfully produce zeoli...

Comparative synthesis of sodium silicate from rice husk and kaolin

Ajayi O. A^*, Mamman J., Adefila S. S.

Sodium silicate in powdered form was successfully synthesized from both rice husk ash and Kankara kaolinite clay. The impure nature of both monomer and NaOH used does not seems to hinder the depolymerization reaction viz-a-viz product formation. The crystallinity of sodium silicate produced tends to increase with reaction time, temperature, and Na2...
