Abstract
Purpose
This paper aims to research the effect of different concentrations for Nd(NO3)3 and Ce(NO3)3 on the microstructures and corrosion resistance of Ni-W-P composite coatings through electroless plating method.
Design/methodology/approach
Scanning electron microscope, attached energy dispersive spectroscopy system and X-ray diffraction were used in this work. Meanwhile, the immersion test and electrochemical tests were used to characterize the corrosion behavior of the coating.
Findings
The coatings prepared at 1.00 g·L−1 Nd(NO3)3 exhibit a dense structure and high phosphorus content (12.38 wt.%). In addition, compared to the addition of Ce(NO3)3, when Nd(NO3)3 was introduced at a concentration of 1.00 g·L−1, the minimum corrosion rate of the coating was 1.209 g·m−2·h−1, with a noble Ecorr (−0.29 V) and lower Icorr (8.29 × 10−4 A·cm−2).
Originality/value
The effects of rare earths on the deposition and corrosion resistance mechanisms of Ni-W-P composite coatings were explored, with the rare earth elements promoting the deposition of nickel and tungsten atoms. Simultaneously, the amorphization of the coating increases, which excellently enhances the corrosion resistance of the coating.

Abstract
Purpose
The purpose of this paper is to investigate, in general, what are the contemporary external influences that have been dominant in Malaysian universities and what are the major local traditional practices that are also found in these universities.
Design/methodology/approach
From the literature review, the paper proposes a conceptual framework to explore hybridity in governance and management, programs and curriculum, teaching and learning, and research and service.
Findings
Using the conceptual framework, the paper discusses the Malaysian higher education in terms of Western influence and indigenization of Western models, the background context of Islamic universities and seven possible hybridities compiled from anecdotal evidences.
Originality/value
The conceptual framework and possible hybridities identified in the paper serve to provide the guide to a more systemic empirical investigation to examine the characteristics of Malaysian universities emerging from the interaction between external influence and local cultures. The Malaysian case also potentially contribute in exploring the question, “Are Asian universities different from Western universities?”.
