Additive Technologies in Metallurgy & Mechanical Engineering

St. Petersburg State Polytechnic University via Coursera

Overview

Every teenager is ready to answer the question - what is 3d printer?
But not every experienced engineer can imagine where and how additive technologies can be applied in mechanical engineering and especially in metallurgy. This is the subject of our online course.

The use of additive technologies is one of the clearest examples of how new developments and equipment can significantly improve traditional manufacturing.
We will consider what additive technologies are for the metallurgical and machine-building industries. For what purposes it is possible to use selective laser fusion, laser cladding and finally detonation spraying.
Which of the world's leading steel companies are already interested in these technologies and how additive technologies can change our future.

At the end of the course you will be able to:
• Additive technologies: what is it?
• Applications of additive technologies in mechanical engineering;
• Applications of additive technologies in metallurgy;
• Prototyping: value and functions;
• Application of selective laser fusion in mechanical engineering;
• Powder materials for SLM technology;
• Gas-thermal spraying of functional coatings;
• Detonation spraying application in metallurgy and mechanical engineering;
• Microstructure and properties of coatings produced by detonation spraying;
• Restoration of parts and accessories with laser cladding;
• The areas of application of complex shape products obtained by direct laser;
• The areas of application of complex shape products obtained by Direct Metal Deposition;
• Microstructure and properties during Direct Metal Deposition
