Introduction to differential equations
Differential equations are any equations that include derivatives and arise in many situations. This free course, Introduction to differential equations, considers three types of first-order differential equations. Section 1 introduces equations that can be solved by direct integration and section 2 the method of separation of variables. Section...

Nitrotec process (oxygen enhanced nitriding)
The Nitrotec process consists of nitriding (nitrocarburising) components, before immediately subjecting them to rapid oxidation, then quenching, finishing with the application of a protective sealant. Oxidation gives protection against corrosion, whilst the quenching and sealing give enhanced surface wear resistance and increased yield strength ...
