Benefits to the User
The primary attractions of APTICOTE 460 to designers
and end-users are its great flexibility and cost effectiveness.
Coatings can be adapted to many different applications by
the careful formulation of specific processing parameters.
- If high hardness is what you need, then APTICOTE
46OG combines this (1,000 Hv) with permanent lubricity.
- Are you working with aggressive or abrasive sticky products, and require
permanent mould release properties? Then specify APTICOTE 460M.
- If you require maximum wear resistance, with excellent mould release, then the answer is APTICOTE 460H.
- Seeking optimum wear resistance with maximum corrosion
resistance? Then APTICOTE 46OC smoothly solves the
APTICOTE 460 can also substantially cut costs
by opening up profitable new materials options.
For example, a part manufactured from low carbon steel
protected by the appropriate APTICOTE 460 corrosion
resisting coating can often replace a more expensive alloy
metal component, with no loss of performance. The poor tribological
performance of stainless steel running against itself is
greatly improved by using APTICOTE 460. Moreover,
the ability to use lower cost material to meet high performance
needs is not the only payback from an investment in APTICOTE
460 coatings. Overall machining costs are considerably
reduced when a part can be made from more workable and more
readily available metals.
Properties and Performance
More information is available on request, but some of the
main advantages of APTICOTE 460 are:
The surface of APTICOTE 460 is smooth and slippery, using low friction polymers.
In many cases, static friction is decreased (as low as 0.06) as the load is increased,
thus approaching total elimination of "stick-slip" and undesirable vibration. For non-stick, mould release applications, APTICOTE 460 utilises polymers with low surface energy.
High Adhesive Wear Resistance
APTICOTE 460 low friction coatings achieve four times the adhesive wear resistance
of electroless nickel in pin-on-disc sliding tests, with hardness
values in the range 750-1000 Hv. Since the outer surface is a polymer,
APTICOTE 460 coatings are not suitable for harsh abrasion situations.
Depending on the formulation, APTICOTE 460 frequently exceeds 1500 hours in salt mist tests, and demonstrates greatly improved corrosion resistance over ordinary electroless nickel coating. APTICOTE 460 also exhibits significant resistance to many commonly used chemicals. (See also our new graded electroless nickel - APTICOTE 400D - it can provide 1000 hours salt spray without the heat-treatment required for our Apticote 460 series, if your component is sensitive to softening or distortion.)
Coatings are applied in thicknesses from 0.0005"
to 0.002' (12 to 50 microns) and to a high degree of accuracy. No post-plating
finishing is necessary.
APTICOTE 460 can be applied to a wide range of
base materials, including aluminium, steels (including stainless
steels), copper alloys and titanium. Finished tolerances
and surface finish are normally related to the conditions
of components before processing. Some post heat-treatment
is often required and may involve temperatures up to 400°C,
depending on material and parameters.
APTICOTE 460 coatings will operate from -115°C
to 260°C depending upon the formulation.
APTICOTE 460 is a highly innovative process and will
readily coat components of complex shapes, all over.
However, the coating can also be applied selectively.
