# Mathematical modelling and computer simulation of nitriding

### WhatIsMathematical Modeling?

We can use words,drawings or sketches,physical models,computer pro-grams,or mathematical formulas.In other words,the modeling activity can be done in several languages,often simultaneously.Since we are par-ticularly interested in using the language of mathematics to make models,3.The Nitriding of Ferrous Powder Alloys - Mathematical Nitriding is a multivariable system that needs the convergence of efforts to allow its improvement.Computer simulation is an important tool to give a simultaneous evaluation of all variables and respective effects in the result of the process.Surface conditions have an important effect in the interaction between gases and metals.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextMathematical Modelling and Computer Simulation of Mathematical Modelling and Computer Simulation of Activated Sludge Systems By Jacek Mkinia;
