1Which Techniques are used for Corrosion
Removal?
byEuroblast Middle East LLC
2Techniques for corrosion removal
- There are numerous corrosion removal techniques
available. - Once you find the type of damage, you can select
the best corrosion removal technique, abrasive
method, and treatment tools for your needs. - Before beginning any corrosion removal technique,
ensure that you have the necessary safety
equipment, including eye, skin, and respiratory
protection.
3Corrosion Damage Assessment
- The first step classify the level of damage. This
is accomplished by thoroughly cleaning and
inspecting the area.
4The following are the categorization criteria
- Light corrosion 0.001-inch-thick peripheral
damage that appears as pitting or discolouration
can be removed with light sanding, polishing, or
chemical treatment. - Moderate corrosion similar to light corrosion,
but with a thickness/depth of up to 0.010 inch
and signs of blistering, scaling or flaking that
can be repaired with manual or power sanding. - Severe corrosion pitting deeper than 0.010
inches, as well as blistering, scaling, flaking,
or exfoliation that necessitates extensive
power-sanding and grinding.
Corrosion below the "light" level may be
considered allowable damage that does not require
immediate repair.
5- Techniques for Removing Corrosion Damage
- The removal technique is chosen based on the
severity of the damage. - Mechanical removal using an abrasives tool is
usually chosen because it is the most effective
and efficient solution. - Abrasive methods can be either by hand or
power-operated.
6Techniques for removing corrosion from Hand
- It is best suited for less severe damage, such as
light corrosion. Often, these minor issues can be
quickly resolved with abrasive paper or abrasive
wool. These solutions are also useful for oddly
shaped parts, tubing, or other equipment that
protrudes from a more uniform surface. - Abrasive Paper Mats
- It is typically filled with silicon carbide or
aluminium oxide abrasive particles. - When accessing corrosion with power tools are
difficult or only a small amount of corrosion
needs to be removed.
7Techniques for removing corrosion from Hand
- Wire Brushes
- Used to remove heavy corrosion deposits.
- Brushes with aluminium or stainless steel
bristles can be used on aluminium. - After wire brushing, the areas may need to be
polished with fine abrasive paper in the case of
aluminium. - Abrasive Wool
- Typically, abrasive wool is used to remove
lighter corrosion deposits. - Aluminum, steel, and stainless-steel wool are
available, and the type of wool must match the
base material.
8Techniques for removing corrosion from Hand
- Scrapers
- Scrapers are used to move an initial layer of
heavy corrosion, but they must be used with
caution so as not to damage the base material. - This is especially true for softer materials such
as aluminium. Aluminium can be scraped with
aluminium, plastic, and carbide-tipped scrapers.
Steel can be scraped with carbide-tipped and
steel scrapers. - Pumice Powder
- Used when very low material removal rates are
required. - The powder is combined with water and applied to
the surface using a cloth. - This method works best on softer materials.
92. Powerful Corrosion Removal Methods
- Powered tools are used to repair more severe
corrosion or damage over a larger area. - The main advantage is their ability to cover
large surface areas quickly. - To avoid overheating, the metal must be allowed
to cool regularly. Power sanding risks are
reduced through proper training and safety
education.
10- Rotary File
- Because this tool can remove a large amount of
material in a short period, it should only be
used by experienced technicians in the most
extreme cases. - Abrasive Blast Media
- Abrasive media comes in aluminium oxide and glass
beads and is ideal for heavily corroded areas. - Radial Bristle Disc
- This is useful for removing stubborn corrosion.
This is only advised for use on aluminium,
high-strength steel, titanium, and magnesium
alloys. Other materials may be harmed by radial
brushes. - Flap Wheel
- These can be used to remove small amounts of
material, but they must be used with caution
because improper use can result in large material
removal rates.
11- Regardless of your best efforts to prevent
corrosion, some will always occur over time due
to exposure to environmental risk factors. - Knowing the different types of corrosion will
allow you to use the best corrosion removal
techniques to solve the problem economically and
efficiently. - Contact an Euroblast Middle East LLC today to
