Rate of corrosion and extend of corrosion depends mainly on two factors i.e.,
- Nature of metal
- Nature of corroding environment
- Purity of metal
- Physical State of metal
- Position of metal in Galvanic series
- Nature of oxide film
- Nature of products of corrosion
- Relative areas of cathode and anode
- Passivation
- Over-voltage
- Temperature
- Humidity
- pH
- Pressure of impurities in atmosphere
- Nature of electrolyte
- Solubility of products of corrosion
- Conductance of corroding medium
- Formation of oxygen concentration cell

∙ 10y agoSome factors that impact the rate of corrosion are temperature, the material being corroded, and the agent causing the corrosion. Acids are very corrosive and can eat away even the toughest materials in seconds.

Will hydrochloric acid corrode 316 sTAINLESS?
Yes it will, the corrosion rate will increase with the temperature but corrosion is already occurring at room temperature.
What effects does ammonia have on steel?
Ammonia reduces the rate of corrosion on steel.
Where is steel used in Rusting out how acids affect the rate of corrosion?
stain
What are the factors which affect rate of diffusion?
the factors which affect rate of diffusion is the factors that mixing one substance to another.
What factors slow down corrosion?
factors that slow down corrosion: 1) coating of paint/wax/oil/polish 2)coating of epoxy paint 3)keeping moisture/oxygen away from metals 4)sacrificial protection 5)keep it with drying agennts
Two factors that determine force of impact?
Mass and rate of deceleration.
What makes the corrosion rate higher in industrial areas than in urban areas?
Taking a look at the industrial areas,the corrosion rate seems to be higher since the industrial area can be said to be a combination of both an urban centre and a rural centre and invariably has a corrosion rate= corrosion rate of urban + corrosion rate of rural areas
Why does corrosion rate of no value on localized corrosion?
in my opinion, the value of corrosion rate obtained from certain reading is generally determine general corrosion rate, regardless what type of corrosion occur on a specific surface. in localized corrosion, where only some spots on surface is exposed to corrosion and other may be covered by film and etc. From my time of study, still didn't fine any research that can determine corrosion rate of localized corrosion unless u have a really micro- instrumentation that can monitor corrosion on the localized spots..

Why would you want to control the rate of corrosion?
You would want to control the rate of corrosion for an object in order to extend the life of that object and/or to be able to observe the corrosion in a controlled situation.
What or 4 factors that effect corrosion?
1) stress corrosion 2) corrosion fatique 3) fretting corrosion 4) heat treatment
What are all the environmental factors causing corrosion?
Corrosion, as in the corrosion of iron into rust, needs two environmental factors: 1. oxygen present in the atmosphere 2. water/moisture present in the the atmosphere
What factors that affect the speed of a car?
What part of an automobile's engine has a direct impact on the acceleration rate of the vehicle as well as what do I do to improve that vehicles acceleration rate.
Will hydrochloric acid corrode 316 sTAINLESS?
Yes it will, the corrosion rate will increase with the temperature but corrosion is already occurring at room temperature.
What natural processes have an impact on the changing shape of Florida beaches?
Corrosion and erosion have and impact on changing the shape of Florida's beaches.
At what temperature does corrosion start?
rate of corossion is directly proportional to temperature
What effects does ammonia have on steel?
Ammonia reduces the rate of corrosion on steel.
Where is steel used in Rusting out how acids affect the rate of corrosion?
stain
