The coating uses nano-scale alumina ceramic powder, with a porosity of less than 1%, and its adhesion strength far exceeds the industry standard, which can resist the scouring of high-abrasive media such as sand and gravel. The unique sintering and curing process ensures that the coating will not crack or delaminate at high temperatures, and it also has excellent acid and alkali corrosion resistance, which can be applied to complex industrial environments with dust and humidity. Compared with the traditional hard alloy surfacing process, it is easy to construct without disassembling the whole equipment, which greatly reduces the on-site maintenance time and cost, solving the industry pain points of long repair cycle and high cost for heavy equipment wear and repair.
The dry film thickness can be selected from 50μm (thin coating type) to 200μm (thick coating type), with HRA hardness of 85-90, adhesion strength ≥25MPa, maximum working temperature of 1200℃, powder particle size of 1-5μm, curing temperature of 800-1200℃, coating density ≥3.8g/cm³, sand slurry wear rate ≤0.01g/cm³. The color can be adjusted to off-white or dark gray according to customer needs, adapting to different equipment appearance requirements. The packaging is 25 kilograms per carton, which is convenient for transportation and storage.
It is mainly applicable to the cavity of mining crushers, the surface of metallurgical rolls, engineering machinery buckets and bucket teeth, the wear-resistant parts of wind power tower cylinders, the grab parts of port loading and unloading machinery, and the press rollers of the papermaking industry. It can provide long-term protection in the continuous working environment of high load and strong friction, effectively reducing the frequency of equipment replacement and operation and maintenance expenses.
