Pin-on-Disc Wear Tester

Approx. component budget: Rs. 10,000 - 15,000

Objective

Measure the friction coefficient and wear rate of different materials (brass, aluminium, polymer, steel) sliding on a steel disc at different loads and speeds.

What you will build

A motor-driven disc with a pin holder, a dead-weight loading arm, a load cell for friction force, speed control and a wear-measuring gauge.

Results you can expect

• Friction coefficient vs time
• Wear volume vs sliding distance
• Wear rate vs load and speed
• Worn surface comparison

What you will learn

Tribology, friction, wear mechanisms and lubricants, used in bearings, brakes and engines.

Tools and notes

Load cell + HX711, tachometer, precision balance (0.001 g), Excel. Guard the rotating disc and keep wear debris under control.

Resume points from this project

• Built and tested Pin-on-Disc Wear Tester; objective: measure the friction coefficient and wear rate of different materials (brass, aluminium, polymer, steel) sliding on a steel disc at different loads and speeds.
• Measured and analysed friction coefficient vs time and wear volume vs sliding distance; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
