Evaluating/estimating corrosion test specimen

5 Whys #
Causes Chain

Get an oxidized model of the specimen

Why?

getting a homogeneous corrosion layer

Why?

corrode the specimen with salt water in a concentration of 3.5% with a volume of 1.5L, in a Pyrex glass cup, and put it on a heat plate at 35 degrees for days, until we see the specimen corroded. adding water every time the system loses util the volume is 1.5L

Contradiction:
If
the amount of corrosion was checked by transmitting a light wave and comparing swallowed wavelengths before and after using the dust remover.
Then
the problem will be solved
But
need to buy sophisticated technological machines with light detectors

    Contradiction:
    If
    the chosen solution is to weigh the model before and after
    Then
    it will be easy to solve the problem without sophisticated technology equipment
    But
    the results are inaccurate and the experiment is unscientific
    Contradiction notes:
    weight the specimen before the use of the rust removal and after

    In past decades, polymeric micropillar devices have gained a great deal of attention in micro and nano technology research as the result of their potential and practical usage in many applications. This project is going to deal with the process of how to fabricate the magnetic micropillars, from the beginning – the planning and design, improving the existing process, lithography to create the base silicon mold and then creating the PDMS pillars that contains nano magnetic particles of Fe_3 O_4, the process today is not efficient enough in terms of cost and time and we are wishing to improve it, in the end we will have a device with micro-pillars that can move correspondingly to external magnetic field which will help us to do many advanced experiments in the biology field like using the device for cell stimulation.
