Corrosion Preventives

Corrosion protection for metals

Unprotected bare metal surfaces lose corrosion, in particular oxidation, which often produces a considerable amount of work surface condition.
This is not only a deterioration of the appearance, but often also an impairment of proper function connected.

The extent of corrosion depends essentially on:

  • the composition and pretreatment of the materials (particularly corrosive, e.g. malleable or gray cast iron)
  • the surface quality of the workpiece (corrosive attack is faster on rough surfaces than on smooth surfaces)
  • climatic influences 
  • other external influences

Corrosion inhibitors such as ANTICORIT from FUCHS serve to protect metallic surfaces against the effects of the atmosphere in the broadest sense and thus prevent the transformation of the metals into their compounds, in particular oxides. 

Basically, a distinction can be made between permanent corrosion protection and temporary corrosion protection.

Permanent corrosion protection offer e.g. paint, galvanic coatings and enamels.
These are difficult to remove by mechanical or special chemical processes. This is often not possible without altering or damaging the metallic surfaces.

ANTICORIT products belong to the group of temporary corrosion inhibitors.
They can be removed relatively easily by solvents or suitable industrial cleaners without damaging the surfaces to be protected. 

It is important that corrosion protection generally has to be optimally compatible with the previous process steps and the products used there.

Our recommendation: the compatible ANTICORIT corrosion inhibitors from the comprehensive corrosion protection program from FUCHS.

 

Selection criteria for corrosion protection products

The relativ large number of ANTICORIT corrosion protection products results from the very different technical requirements. 
The following table gives a short overview of the main aspects concerning the choice of the right corrosion preventive for a specific application. 

aspects

criteria

to note:

Protection period

weeks, months, years

The protection periods have to be considered with full knowledge of the storage facilities, means of transportation and the packaging.

Type of film

oily, oily-thixotropic, greasy, wax-like, paint-like

Draining properties, grip, dust suppression, slickness, compatibility with packaging, stickiness.

Application method

brush, immersion, spray, drip

Surface geometry, size of the parts, individual parts or bulk series, dimensions and space, film thickness control, issue of solvents.

State of the parts during application

dry, humid, wet, cleanliness, temperature, movement

Dewatering, compatibility with the lubricants used in the preceding forming process, cycle, throughput speeds.

Further processing

machining, forming, surface treatment, assembly

Adhesion in collet chucks, forming lubrication, weldability, emergency lubrication, compatibility with lubricants.

Removal

wiping, aqueous alkaline cleaners, aqueous neutral cleaners, aqueous acicic cleaners, solvents - liquid, solvents - vapour phase

Normally, the higher the protection effect the more difficult the removal.

Storage conditions

cleanliness, transportability, stackability, touchability, measurability and testability, appearance

The storage conditions are to be defined and complied, with using clear criteria, in order to achieve optimum protection effect.

Transportation

overland transportation within the company, transportation by sea and tranportation by air

A high air humidity and climatic conditions falling below the dew point have an influence on the protection period.

Economic efficiency

landed costs, economy in use, application costs, removal costs, degree of damage through potential complaints

Only the total of all costs is a measure of the economic efficiency.
