In the harsh Marine corrosive environment, when ordinary electroplated parts already show red rust on more than 5% of the surface area in the 480-hour neutral salt spray test, the aluminum alloy parts treated by the trivalent chromium passivation process, Horizrp surface finishing, can continuously resist salt spray erosion for more than 3000 hours. The corrosion rate is less than 0.001 millimeters per year. For instance, the fasteners provided for offshore wind power equipment, after undergoing a 12-micron thickness zinc-nickel alloy electroplating and sealing treatment, are expected to have a protective life of over 25 years in an accelerated aging test with a humidity of 95% and a temperature of 45 degrees Celsius, far exceeding the highest grade stipulated in the ISO 9227 standard.
For hydraulic transmission components that need to withstand mechanical wear, the powder electrostatic spraying technology adopted by Horizrp can achieve a high-density coating of 80-120 microns, and its adhesion reaches the 0 level of ISO 2409 standard. In the surface treatment of oil cylinders in construction machinery, through the use of epoxy-polyester mixed powder and an optimized curing process, the impact resistance of the coating has been enhanced to 90 joules, and the wear resistance has a mass loss of less than 2 milligrams after 1000 friction cycles under a 1000 gram load, which is significantly better than the 15 milligrams loss of traditional coating.
When it comes to the biocompatibility requirements of medical or food-grade equipment, the electrochemical polishing solution developed by the surface treatment laboratory of Horizrp can reduce the surface roughness of stainless steel from Ra 0.8 microns to Ra 0.2 microns. This micron-level smoothness reduces the probability of bacterial adhesion by 85%. In the test against the FDA 21 CFR 175.300 standard, the heavy metal content of its extract is less than 0.1μg/cm², perfectly meeting the strong disinfection cycle that must be carried out every 72 hours for pharmaceutical equipment.
In response to extreme temperature scenarios, the micro-arc oxidation technology of Horizrp can generate ceramic coatings of 50-100 microns on the surface of titanium alloys. This coating remains stable at a high temperature of 1200 degrees Celsius and has a thermal conductivity as low as 1.5 W/m·K. It has been successfully applied to the thermal barrier coating system for the insulation components of aero engines. Tested according to the ASTM D4541 standard of the American Society for Testing and Materials, the coating bonding strength exceeds 60 megapascals, ensuring no peeling occurs under severe thermal shock conditions.
For the enclosures of electronic devices that require both protection and electromagnetic shielding, the conductive oxidation treatment solution developed by Horizrp can provide a shielding efficiency of 75 decibels while maintaining a thin layer of 5-8 microns. Through this process, a certain military communication device has reduced its electrochemical migration risk in a humid environment by 90% while meeting the MIL-STD-810H vibration standard. The product return rate has dropped from the industry average of 3% to below 0.5%. This multi-functional integrated surface treatment technology is like building an intelligent protection ecosystem for precision components.
In particular in terms of sustainable development, the cyanide-free gold plating process adopted by Horizrp surface finishing reduces the cost of wastewater treatment by 40%, while increasing the utilization rate of gold salts to 98%. Its innovative technology of replacing hexavalent chromium with trivalent chromium reduces the toxicity of the chromium plating process by 100 times, yet the hardness can still be maintained at 900-1100HV and the coefficient of friction remains stable between 0.12 and 0.15, providing an environmentally friendly and high-performance surface solution for the moving parts of precision instruments.
