Surface Integrity Analysis of Duplex Steel by Design of Experiment Approach

Separation of solids and liquids from water is an actual problem in the water waste, chemical, oil, and food processing industries. The purpose of water treatment facilities is to purify water which contains minimal amounts of solids and liquids and at the same time this technology should allow to process large amounts of water and be energy-efficient. That is why a new type of counter flow decanter centrifuge was constructed and appropriate experiments on prototype production were carried out to optimize machining parameters. Output data were analyzed by statistical methods. As a result of these experiments statistically significant factors that affect surface integrity were determined.
