Surface finishing is a critical process in manufacturing and engineering that enhances the surface quality of materials such as metals, plastics, and composites. It involves techniques like polishing, grinding, sandblasting, electroplating, and coating to achieve desired properties such as smoothness, corrosion resistance, aesthetic appeal, and improved functionality. By removing imperfections, reducing roughness, or adding protective layers, surface finishing extends the lifespan of products, improves their performance in applications like automotive parts, electronics, and medical devices, and ensures compliance with industry standards for durability and safety. This process is essential for optimizing both the visual and functional aspects of a finished product, making it more reliable and market-ready.

A) The maximum peak height
B) The average roughness value
C) The total surface area
D) The depth of valleys
Answer: B
Explanation: Ra is the arithmetic average of the absolute values of the profile height deviations from the mean line, indicating overall surface texture.
4. Which process is commonly used for applying a protective oxide layer on aluminum?
A) Sandblasting
B) Anodizing
C) Polishing
D) Electroplating
Answer: B
Explanation: Anodizing creates a durable, corrosion-resistant oxide layer on aluminum through an electrochemical process.
5. In surface finishing, what is the main advantage of electroplating?
A) It reduces electrical conductivity
B) It provides a decorative and protective coating
C) It increases surface porosity
D) It hardens the internal structure
Answer: B
Explanation: Electroplating deposits a thin metal layer that enhances appearance, wear resistance, and protection against corrosion.
6. Which surface finishing technique uses high-pressure air mixed with abrasive media?
A) Buffing
B) Sandblasting
C) Vapor degreasing
D) Tumbling
Answer: B
Explanation: Sandblasting cleans and roughens surfaces by propelling abrasive particles at high speeds to remove contaminants.
7. What is the typical outcome of polishing a metal surface?
A) Increased friction
B) A mirror-like finish
C) Surface pitting
D) Brittle material
Answer: B
Explanation: Polishing uses fine abrasives to create a smooth, reflective surface that reduces roughness and improves shine.
8. Which factor is most important when selecting a surface finishing method for medical devices?
A) Cost only
B) Biocompatibility and sterility
C) Color variety
D) Weight addition
Answer: B
Explanation: Surface finishing for medical devices must ensure biocompatibility to prevent reactions and maintain sterility for safety.
9. What does shot peening do to a metal surface?
A) Softens it for easier machining
B) Introduces compressive stresses to improve fatigue resistance
C) Removes all surface layers
D) Increases tensile strength directly
Answer: B
Explanation: Shot peening bombards the surface with shots to create compressive stresses, enhancing durability against cracking.
10. In powder coating, what is the role of the curing process?
A) To remove the powder
B) To fuse the powder into a smooth film
C) To add moisture
D) To increase porosity
Answer: B
Explanation: Curing heats the powder coating to melt and chemically bond it, forming a durable and uniform protective layer.
11. Which surface finishing method is best for achieving a matte finish on plastics?
A) Electroforming
B) Bead blasting
C) Chrome plating
