Surface Technology - First in finishing
In the current UK climate engineering is becoming more specialised. To service this need a high degree of expertise is required to complement the products and services that will survive. Demands on corrosion protection, wear and aesthetics, coupled with the ever present pressure to reduce the environmental impact require specialists in each field.
Firma-Loy is such a specialist. Our aim is to make available all the best techniques, the most responsive service on one site where the environmental impact will be contained & eliminated where possible. |

Electroless
Nickel
No electrical current is applied, instead a metallic coating is deposited from the controlled chemical reduction of a metal salt.
The resulting product is uniform in thickness over all surfaces including threads, bores and recesses.
It is possible to coat almost all metals up to a thickness of 100 microns
(.004")
The standard of finish on the component is important as the coating reproduces the substrate surface finish.
The coating is relatively hard as plated but can be heat
treated at low temperature to increase surface hardness to approx. the
same as hard chrome.

Hard Chrome
A hard, low friction, wear and scratch resistant metal coating up to 50 micron
(.002") thick. Ideal for cutting and slicing blades, sharpening steels. pistons and drill bits.
It is also used for anti-galling and anti-fretting purposes particularly on
''stainless steel to stainless steel'' applications. Work produced on our automatic plant is ideal for high volume work where an extended wear life and a semi decorative finish are the main criteria |

Phosphate
A relatively thin chemical conversion coating used mainly on
steel. It converts the surface layer, forming a porous crystalline layer which acts as a corrosion retardant. Major applications include pre-treatment prior to organic coatings,
"bedding in" of gear, clutch and disc products, and anti wear and corrosion protection when used with a suitable supplementary coating absorbed into the surface. |
