TITLE:
A method for producing alkaline earth metal salt based soft coatings on
multishaped metallic structures.
FIELD OF THE INVENTION:
This invention relates to a method for producing alkaline earth metal salt
based soft coatings on multishaped metallic structures.
BACKGROUND OF THE INVENTION:
Complex shaped metallic structures are susceptible to corrosion at the edges
and curvature points. The metallic tubes are highly corrosion
susceptible,especially at their weld-able zone because of lacking in same
specification of metal as found in other parts. Therefore, it is necessary to
develop some formulation and methodologyfor mitigate the corrosion
problems in complex shaped metallic structures. Metal to metal friction may
cause the corrosion so wear prevention should also be maintained during
packaging, in online running line, transportation, storage and exposure of
rainy and humid atmosphere.
In recent, many of the coating formulations and non-drying rust preventive oils
have been developed to get better corrosion resistance and lubrication but

now the use of RPO has been obsoleted due to their non-adherence nature
on metals which may again increase the uptake of corrosive ion.
Researchers are advancing to develop the material which can save the time
and improve the performance as well. For this purpose, they are focusing the
material application during formation of steel in running line. Since steel
cutting and cooling consumes a lot of coolant inside and outside as well so the
prepare steel is already has some coolant over it i.e low tensed surfaces. The
challenge is to produce the formulation for low tensed surfaces b) high friction
may occur in running line so the challenge is to produce the formulation for
wear prevention.
For offline application, it is easy to develop the hard dried coatings but they
may be not feasible to the online application. So in this invention, with keeping
the all object, we have produced aalkaline earth metal based
soft/semidrying/drying up to tack free coating formulations which applicable on
low tensed surfaces by forming a dense thin layer, enhancing the water
repellent, reducing the uptake of corrosive ion and excellent wear prevention.

and lubricity vi. putting altogether into a vessel and mixing by mechanical
stirrer at 400 rpm for 30 minutes v. applying this solution on multi-shaped

Hereto, both invention is useful for automobile industry (Bolts, threaded parts,
tire trims, shock absorber and handle bar), oil industry (inside the condenser
box,' condenser oil), gas industry (Coal handling equipment, inside air and
water tanks), structural applications, plumbing applications.
The properties and ingredients of both inventions are shown in Table 1 and 2
respectively. Obtained FT-IRpeaks of resin part i.e oxidized hydrocarbon and
coating solutionsof both inventionsis demonstrated by FT-IR pictogram shown
in Fig. 1 and Fig.2.

In present invention, the film properties of both coating solutions are
approximately same, only the difference in corrosion resistance of the film to
the non-spangled galvanized substrate as shown by Fig.3 and Table 2. The
present invention is providing the coating solutions, exhibiting good corrosion
resistance. Calcium and barium based coated surfaces showed good
corrosion resistance in the range of 10-8 factor.
According to the ASTM D 2266, both inventions provide excellent lubricity and
wear prevention determined by four ball wear test method. The low level of
coefficient of friction (example 1: 0.0912; example 2: 0.0932) between coated
steel to steel (steel rollers) at 1200 rpm for 60 minutes in ultrasonic vibrator at
75 degree temperature by supplying the test load of 40 Kg and measure the
wear scars (average scar diameter of three test balls is 0.49 mm in example 1
and 0.63 mm in example 2) on the three balls fixed in ball cup with one ball
fixed in ball chuck below the three balls into the ultrasonic vibrator. The void
between balls is filled by coating solution (example 1 and 2).
The present invention provides the coating solution, having low or same
surface energy required to be applied on coolant drenched metallic surface
and water repellent properties required for providing water hydrophobicity.

The present invention provides the surface energy of coated galvanized
sample which is deduced by considering two liquid's contact angle on coated
substrate (One liquid is water and another is acetone) and their polar,
nonpolar components. Both coating solution (example 1 and 2) show lower
surface tension {Example 1:3.39mN/m (45.46 - 42.07) and Example 2:
4.14mN/n (45.46 - 41.32)} than the surface tension of coolant (51.89-45.46 =
6.43mN/m) which indicates the coating applicability on coolant drenched
surface. So both coating solution's surface tension and coated surface energy
is lower than solution of coolant's surface tension and coolant soaked surface
energy which is desired property for coating applicability on wet/coolant
soaked surface.
The said coated sample of example 1 and 2exhibits water repellent properties
(contact angle of coated sample of example 1:109.7° and example 2: 109.1°)
