Abstract:
Abstract: The course topics to be taught are intended to serve as a tool for understanding the corrosion process. Ways to prevent corrosion and treat corrosion damage.
The appearance of corrosion in the products can cause damage worth millions of dollars. Investing thought in the high school product stages will prevent corrosion damage during the processing and manufacturing processes, during the processing processes, including storage time, raw materials in product storage and during use.
The course was prepared as an aid to the planner on the subject of corrosion engineering.
The first 2 chapters form a background on the subject of metallurgy and electrochemistry, the following chapters discuss the different types of corrosion - shapes and means of protection (coatings, painting).
Later, the student will be prepared to prepare models, a quick stay to receive a corrosive attack and to prepare metallographic models, after various experiments or models that are attacked in a hostile atmosphere (taken from the field and a hostile atmosphere). These are various, common means of protection for metals and finished parts to prevent corrosion. Surface protection will include conventional metals, piping, iron alloys, aluminum alloys (castings) and copper alloys (decorative coatings).
At the end of the transfer of the theoretical material Corrosion and Protective Measures, the students will visit to illustrate the material studied in a coating plant and will demonstrate methods and protective methods accepted in Israel for corrosion prevention.
Course / Module aims After the transfer of the topics mentioned, the student must know how to use a tool that has been given "corrosion" in high school (the final thesis). What measures should the student take to prevent the corrosion phenomenon in storage and protective measures in production.Abstract:
We often hear a bridge collapse, a crane destroyed or a plane crash due to"material fatigue" or other structural failure. Is it possible to detect and prevent such events?
The reply is Non-Destructive Testing or NDT. These tests are applying known
physical theories on the part and so determine if it has any defects and if they are acceptable.
In most cases we use secondary effects to realize the internal or the latent state of the part.
Parts are tested as sample or in full depends or the criticality of the use.
The traditional NDT methods are:
Radiography – Internal viewing by X-Ray
Ultrasonics – Analysis of sound wave signal that permits detection of internal Defects
Magnetic Particles – analyses of disturbances of the magnetic field lines on the part surface
Dye Penetrants – bases on capillarity that entraps coulr inside open toi the surface discontinuities
Eddy Current – Flaw detection based on difference in the material
conductivity due to internal discontinuities
