HDFB-Coupling assembled to gearbox shaft and metallic conveyor drive (HENFEL)

The sugarcane industry is one of the most flourishing segments of the Brazilian Economy. With a production of up to 624 million metric tonnes of sugarcane in the 2017 harvest season, the country holds the world record production for both sugar and ethanol from this raw material. A broader view reveals that more than 37 million tonnes of sugar and 27 million cubic meters of ethanol were produced to meet national and expanding global demand. 

Regardless of the application for which a coupling is used – a variety of requirements must be fulfilled to ensure efficient and reliable operation of the coupling system. Undoubtedly, the coupling is a vital component of the entire propulsion line. Therefore, when designing a coupling, attention must be paid that the coupling is able to withstand the mechanical requirements, requires virtually no maintenance, operates trouble-free and, ideally, has a long service life.

This is part 3 of our series on surface treatments of components. Due to the great number of different chemical processes, we have split them up and explored these processes in the previous article:

• Chromate conversion coating
• Phosphating
• Galvanizing
• Plating
• Black oxide.

This blog article covers the remaining chemical processes commonly applied for the treatment of component surfaces.
