Coating Service

UniqueCoat Technologies operates a fully featured modern spray shop. Large and small parts can be coated accurately and efficiently, with consistent coatings from start to finish. We can handle large batches of parts or small runs. No matter what size, shape, or weight, we will find a way to spray it. Call today for a free quotation.

Why AC-HVAF is better

Solid particle technology:

provides continuous self-cleaning effect
minimizes amount of prep work necessary before spraying
produces extremely dense coatings
particles do not pull away from each other as they cool
decarburization of carbides eliminated
provides better wear resistance in coatings
improves fatigue performance

Consistent, high coating quality:

<0.2% porosity
<0.1% oxide content (comparable to raw material level)
low coating stress levels allow thick layers to be applied

Unique structure:

prevents crack propagation and delamination

Low cost due to:

high deposit efficiency
use of compressed air instead of oxygen
air cooling of gun instead of chilled water
fuel alternatives
low consumption of spare parts
very high spray rates
targeted application of coating where needed

Low implementation cost:

small footprint
no large tanks

Industrial Applications for AC-HVAF

Centrifugal fan blades	A thin coating of tungsten carbide increased the life of the part from 1,200 hours to 9,000 hours.
Copper rolls	Quickly increased diameter of roll, low oxygen content, electrical resistivity lower than cast aluminum, any size roll can be coated, coatings do not peel off
Galvanizing line	Coating prevents dross from sticking to sink rolls
Power generation	Coatings prevent high temperature corrosion and erosion of boiler water walls, protect turbine components, and reduce wear on augers and screens
Oil drilling	Coatings prevent corrosion and abrasion of down-hole pipelines to increase life expectancy from 2 weeks to 52+ weeks

Hard Chrome Replacement

Hard chrome plating has come under scrutiny because of its environmental hazards. The plating process produces hexavalent chromium, a known carcinogen. Environmental regulations are becoming increasingly strict, putting pressure on chrome plating shops to invest in new equipment or shut down. Because of this, the price for hard chrome is increasing while availability is decreasing.

AC-HVAF is an excellent “green” alternative to hard chrome plating. There are no hazardous fumes to contain, and the overspray can be recycled. UniqueCoat Technologies offers several materials which can replace hard chrome plating. These materials provide much better wear protection and other enhanced properties. They also have the advantage that they can be applied in a targeted area as needed in order to minimize the application cost.

Coatings of the most popular Tungsten Carbide-based compositions are applied onto roll surfaces and superfinished to better than Ra 0.3 micro-inch roughness. Such surface quality became possible due to the superior density of AC-HVAF coatings and absence of brittle phases which are usually formed due to oxidation and thermal deterioration of carbides in other thermal spray processes.

AC-HVAF WC-based coatings are noticeably harder than hard chrome, exhibit better toughness and can be applied to practically any thickness, providing armor-like performance during service. Contact us today to discuss your application. We will suggest a coating material to meet your needs.
