Metal production: considering the environment

While there is always the economic incentive in production processes, the environmental impact of metal production is also under consideration. Metal producers must consider their environmental footprint. Hence, researchers seek out alternative energy sources such as solar or biomass. Making industrial processes ‘green’ helps reduce waste and pollution.

The steps of sample preparation in metallography

Metallography concerns the examination of metal, and other materials’, microstructures.

These are the steps in sample preparation:

1. Sectioning: using an abrasive tool to acquire a piece of material.
2. Mounting: the sample is mounted in a compatible material, usually plastic or epoxy.
3. Grinding: using an abrasive wheel.
4. Polishing: any remaining deformations are removed, and a smooth surface is produced.

What are diamond suspensions?

Diamond suspension is used in the polishing step of sample preparation; it functions as the abrasive. Akasel manufactures a 2-in-1 diamond suspension solution that contains both diamond suspension
and lubricant. Lubricant is included because it assists in high removal rates and reduces scratches and polishing time. Akasel’s 2-in-1 suspension is designed to ensure easily reproducible preparation results with every use.

It is important that the optimal amount of suspension is used in polishing. The carefully balanced mixture from Akasel makes measuring doses easy; only one dose needs to be determined, whereas a separate diamond suspension and lubricant would pose two manual dosage measurement requirements.

Any industry that benefits from metallography can benefit from this product.

Why is metallography important?

All industries seek to provide the best solutions in their respective fields. Metallographic studies allow industries to determine which materials are ideal for particular constructions. Alongside physical laboratory studies, there are software solutions for modelling possible microstructures, to see how they would behave. Since the microstructures of metals can be modelled, it is possible to predict properties at larger scales.
