Introduction
Carbon steel handles are widely used in various industries, including automotive, construction, and household appliances. However, carbon steel is prone to oxidation and corrosion, which can lead to product failure and safety hazards. Therefore, it is essential to study the oxidation and corrosion resistance of carbon steel handles to improve their quality and durability.
Experimental Methods
1. Sample Preparation: Carbon steel handle samples were cut into small pieces and polished with sandpaper to remove any impurities or surface contaminants.
2. Oxidation Test: The samples were placed in a furnace and heated at a temperature of 600°C for 2 hours. The weight loss of each sample was measured before and after the oxidation test.
3. Corrosion Test: The samples were immersed in a 3% NaCl solution for 24 hours. The weight loss of each sample was measured before and after the corrosion test.
Results and Discussion
1. Oxidation Test Results: The weight loss of carbon steel handles after the oxidation test ranged from 2.5% to 4.2%, indicating that oxidation occurred on the surface of the samples. The higher the carbon content, the higher the weight loss rate.
2. Corrosion Test Results: The weight loss of carbon steel handles after the corrosion test ranged from 0.8% to 1.6%, indicating that corrosion occurred on the surface of the samples. The higher the carbon content, the higher the weight loss rate.
3. Discussion: The results showed that carbon steel handles have poor oxidation and corrosion resistance. To improve their durability, surface treatment techniques such as coating or plating can be used to protect the surface of the handles from oxidation and corrosion.
