    Advances in Concepts of Ergonomics with Recent Industrial Revolution
    (International Conference on Engineering for Sustainable World, 2021) Fayomi, O.S.I.; Akande, I.G.; Essien, V.; Asaolu, A.; Esse, Ugwunwa C.
    Change is constant and as such we must always look forward to ways to help us adapt to this changes. With constant improvement being revised on evolving better and improved ways in which individuals and workers can function in their various organizations and industries, better and improved methods would have to be constantly developed in order to gain maximum efficiency from workers. The emergence of the Industry 4.0 industrial stage era has witnessed with its arrival tremendous industrial performance. This paper seeks to provide a review on the various advances of ergonomics concepts with the advancing industrial revolution with supporting roles on importance of training workers on the new innovative techniques

    Experimental studies and influence of process factor on zinc-nickel based coating on mild steel
    (Taylor & Francis: Advances in Materials and Processing Technologies, 2021-03) Fayomi, O.S.I.; Sode, A.A.; Anyanwu, B.U.; Ayoola, A.A.; Nkiko, Mojisola O.; Oluwasegun, K.M.; Alkhuele, D.O.; Ighravwe, D.E .
    Sulphate-rich electrolytic bath containing ZnSO4.7H2O in NiP solution was used to develop coating with Ni-P-Zn matrix under optimised process parameter. The major considerations are to examine the factor variance and the effect of varying time parameter between 10, 15, 20 and 25 min on the developed coating. Wear loss evolution was examined using reciprocating sliding wear tester with a force of 10 N and 20 N. The microhardness behaviour was examined using durascan microhardness tester with diamond indenter. The change in the structural build-up and the corrosion performance trend was observed using a scanning electron microscope enhanced with energy dispersive spectroscopy and potentiodynamic polarisation route. From the result we observe that time-dependant factors impact maximally on the crystal growth which rightly influences the coating hardness performance. For wear performance, the counter with external forces couldn’t penetrate wholly into the lattice of the developed coating due to the resilient formation of stable flakes. The microstructure formation shows stable dispersed crystal build-up and homogeneous growth. An excellent corrosion resistance characteristic was noticed with Ni-P-Zn-25 min matrix.

    Review of metal protection techniques and application of drugs as corrosion inhibitors on metals
    (International Conference on Engineering for Sustainable World (ICESW 2020), 2021) Nduma, R.C.; Fayomi, O.S.I.; Nkiko, M.O.; Inegbenebor, A.O.; Udoye, N. E.; Onyisi, O.; Sanni, O.; Fayomi, J.
    The inability of metals to resist degradation as a result of corrosion remains a unique global problem that depend on different metals for daily operations. Therefore, knowing the appropriate method to use is a key to ameliorate corrosion effect on metals. Green inhibitors serve as a modern, cheaper and environmentally favorable method to retard the effects of corrosion. Drugs are corrosion inhibitors which can reduce the action of corrosion without being hazardous to the environment as they are synthesized from natural products. The review studies the metal protection techniques and the use of drug as corrosion inhibitors. The importance of copper as a useful metal as good corrosion resistance due to inherent properties alongside its malleability was also discussed.
