Mechanical Parts
When selecting materials and surface finishes for mechanical parts, engineers must consider factors like strength, wear resistance, corrosion resistance, aesthetics, and cost. Below is a comprehensive breakdown of common options:
Metals
Steel
Carbon Steel (e.g., 1018, 1045): Good strength, machinability, and cost-effectiveness.
Alloy Steel (e.g., 4140, 4340): Higher strength, toughness, and wear resistance.
Stainless Steel (e.g., 304, 316): Corrosion-resistant, used in food/medical/aerospace.
Tool Steel (e.g., D2, H13): High hardness for cutting/die applications.
Aluminum (e.g., 6061, 7075): Lightweight, corrosion-resistant, easy to machine.
Copper & Alloys (Brass, Bronze): Good conductivity and corrosion resistance.
Titanium (e.g., Grade 5): High strength-to-weight ratio, biocompatible, aerospace/medical use.
Magnesium Alloys: Ultra-lightweight but flammable (used in aerospace).
Nickel Alloys (Inconel, Monel): Heat/corrosion-resistant for extreme environments.
Plastics/Polymers
Engineering Plastics:
Nylon (PA): Wear-resistant, used for gears/bushings.
Delrin (POM): Low friction, high stiffness.
PTFE (Teflon): Chemically inert, non-stick.
PEEK: High-performance, heat-resistant.
Thermosets:
Epoxy, Phenolic: Used for insulation or high-temp parts.
Other Materials
Composites (CFRP, GFRP): Lightweight and strong (aerospace/automotive).
Ceramics (Alumina, Zirconia): Extreme hardness/heat resistance but brittle.
2. Surface Finishes for Mechanical Parts
A. Functional Finishes (Improve Performance)
Anodizing (Aluminum/Titanium):
Enhances corrosion/wear resistance; colors available (Type II/III).
Hard Coatings:
Hard Chrome Plating: Wear-resistant, low friction.
Electroless Nickel Plating: Uniform coating, corrosion resistance.
DLC (Diamond-Like Carbon): Ultra-hard, low-friction.
Thermal Spray (HVOF, Plasma Spray):
Applies coatings like tungsten carbide for extreme wear.
Case Hardening (Carburizing/Nitriding):
Hardens surface while keeping core tough (e.g., gears).
B. Corrosion Protection
Galvanizing (Zinc coating for steel).
Passivation (Stainless steel, removes free iron to prevent rust).
Powder Coating: Durable, decorative polymer layer.
C. Aesthetic Finishes
Polishing/Buffing: Mirror-like finish (stainless steel, brass).
Bead/Sand Blasting: Matte texture, removes burrs.
Brushing: Directional satin finish (common for appliances).
PVD (Physical Vapor Deposition): Thin, decorative/metallic coatings (e.g., gold, black oxide).
D. Specialized Treatments
Laser Engraving/Etching: Permanent markings.
Tumbling/Vibratory Finishing: Deburring and smoothing edges.
3. Selection Considerations
Environment: Saltwater? High temp? (Choose stainless, nickel alloys, or coatings like anodizing).
Wear: Use hardened steel, DLC, or ceramic coatings.
Cost: Carbon steel + plating may be cheaper than stainless.
Dimensional Tolerance: Some coatings (e.g., electroplating) add thickness.
