DESIGN BACKGROUND STUDENT PERCEPTION ON THE TEXTURE OF LIGHT METAL SURFACE TREATMENT
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2018, Vol 7, Issue 1
Abstract
Being lightweight, recyclable, highly moldable, and fast cooling, light metal materials are suitable for many types of processing and surface treatments. Advances in technology have further widened their range of applications, and the number of products using light metals (such as the cases of cell phones or tablet computers) has increased in the last few decades. This study uses aluminum alloy, the most typical application of light metals, as the material. The material was processed using the five most typical surface processing methods (i.e., hairline, sand blasting, polishing, anodizing, and turning), and the resulting textures were used as the contributing attributes to the mental images perceived by the users. Using Semantic Differential method, one hundred twenty subjects were asked to check on five categories of 15 pairs of adjectives that described the potential mental images. The final analyses focused on finding Factor analysis of the perceived characterizations of the texture by the subjects generated three factors. 1. The Activity factor consists of seven (7) pairs of opposing adjectives: Curved/Straight, Soft/Rigid, Natural/Artificial, Organic/Geometric, Dynamic/Static, Light/Heavy, Variable/Monotonous. 2. The Evaluation factor consists of six (6) pairs of opposing adjectives: Industrial/Artistic, Trendy /Traditional, High-value/Low value, Stable/Fluid, High quality/Low quality, Extravagant/Simple. 3. The Style factor consists of two (2) pairs of opposing adjectives: Decorative/Practical, Personalized/Popular. In the Activity factor, the Curved/Straight pair was ranked the highest. In the Evaluation factor, the Industrial/Artistic pair was ranked the highest. In the Style factor, the Decorative/Practical pair was ranked the highest. The subjects and the two groups of subjects with different educational backgrounds displayed did not show significant differences in their perceptions of the five aluminum alloy textures in terms of gender. In terms of their preferences, the five textures ranked polishing > hairline finishing > sandblasting > turning> anodizing.
