 An ambient-dead separation of nickel-phosphor alloys
features a set of vantages and achieves frequently
requirements which are not attainable with other
treatments.
Different phosphoric contents of nickel-coatings result
in a broad range of applications, e.g. protection
against corrosion and abrasion.
For more than 25 years and due to highest expectations of autocatalytic segregated nickel-phosphor layers (10.5 – 12% phosphor) MTV decided to utilize high-phosphoric procedures.
 In addition to outstanding protection against corrosion and abrasion, a coplanar separation of chemical fabricated layers spotlights a particular feature.
Compared to electrolytic separated layers,
autocatalytic generated nickel-coatings can be
manufactured in favor to complex geometric shapes, so that a steady allocation of the required coat thickness occur – entirely independent of the component´s stature.
 MTV´s high-phosphoric chemical nickel baths are diffusion resistant and gain the capability to be used as a diffusion barrier between precious materials, steel and copper.
All metals including their alloys are applicable for chemisch-nickel surface coating.
In the event of a processing error or future unit reparation, chemical-nickel parts can be stripped without any interference of the base material.
The high-phosphoric layers with more than 10.5 mass
percentage of phosphor are semi-bright, x-ray amorphous
in structure, very ductile and display a compressive stress. Furthermore, the compliance to requirements MIL-C-26074B, AMS-2404B, DIN 50966, RAL-RG660 part 2 of quality control association (4.4) of intense corrosion exposure is given.
 MTV refines high-phosphoric nickel-layers since the early 1980´s with a particular and constant enhanced chemical- and systems-engineering.
Autocatalytic and accurately outlined generated, even on vast geometric and complex molded components, these workpieces comply with highest requirements of corrosion prevention and wear protection. They are diffusion resistant (>25 µm) and provide an outstanding abrasiveness next to proper ductility - which can be increased by a selective heat treatment -at the expense of resistance to corrosion- up to 1000 HV.
The actual immersion-treatment capacitiy enable MTV to manufacture units with 2500 mm in diameter, in certain cases up to 5000 mm. Special parts can be coated in specially assembled basins or lined-up tanks if required.
