SUPERB COVERAGE

The Surface Technology Group (STG) works to enhance competitiveness of the local industry through research, generation and application of innovative coatings and surface engineering processes, and through training technology specialists. The group aims to be a leading R&D centre in surface technology, developing high performance coatings and surface engineering technologies to make products more cost effective, while increasing functionality, productivity, and useful life cycle.

Towards this goal, the group has built up core competence and expertise in: (1) Functional coating design and characterisation, (2) Materials synthesis and chemical formulation, (3) Coating deposition processes, and (4) Surface chemical modification and structuring.

Research activities have concentrated on coating development using hybrid composite materials. Novel or multiple coating functionalities have been realized through innovation in materials engineering and processing. Coating process capabilities established range from physical vapour deposition, chemical vapour deposition, sol-gel deposition, electrolytic and electroless plating, anodizing and surface conversion coating, surface structuring or micro-fabrication by photolithography chemical etching/deposition and surface self-assembly.  

Technical focus of STG is on coating technologies for applications in precision engineering (PE), aerospace, marine, automotive, bio-engineering, optical, electronics, environmental and clean energy, consumer appliances and construction industries. Targeted functions include wear and scratch protection, dry lubrication, transparent conductors, corrosion protection, easy-clean and other surface properties such as, self-cleaning, anti-microbial, anti-slip, and photochromic smart coatings.
