A mechanically robust, self-cleaning, highly abrasion-resistant superhydrophobic composite coating, method and applications thereof
This invention belongs to the field of new materials, specifically relating to a mechanically robust, self-cleaning, highly wear-resistant, and superhydrophobic composite coating, its method, and its applications. Using epoxy resin (E51) as a binder, this invention combines quartz sand, modified F-TiO₂ nanoparticles, and SiO₂ nanoparticles to prepare a two-layer quartz sand / F-TiO₂ / SiO₂@EP superhydrophobic composite coating through a simple scraping-spraying process. This coating, through multi-scale hierarchical structural design and low surface energy modification, achieves a static water contact angle of 151° and a roll-off angle of <5°, exhibiting excellent self-cleaning performance against liquid and solid contaminants. Mechanical stability tests show that the coating maintains good hydrophobicity after 3000 cycles of wear under a 250 g load and 600 cycles of wear under a 750 g load in the Taber abrasion test; after 500 tape peel tests, the static water contact angle is still greater than 120° and the roll-off angle is as low as 5°, demonstrating excellent abrasion resistance and substrate adhesion.

Abrasion tester device enhanced by artificial intelligence and image processing
PCT designated stageWO2026127915A1Image analysisBiological neural network modelsImaging processingWear testing
Abrasion Tester Device Enhanced by Artificial Intelligence and Image Processing Abrasion testing devices are used to measure the resistance of material surfaces against mechanical abrasive effects such as friction, rubbing, and erosion. These devices are widely employed across various industries to determine the wear performance and long-term durability of materials. The results of abrasion tests may vary depending on the expertise of the operator and the environmental conditions under which the test is conducted. The invention enhances the accuracy and objectivity of abrasion tests by integrating artificial intelligence and image processing technologies into the abrasion testing device. In this way, the measurements become more precise and reliable. Furthermore, by reducing the need for operator intervention, human-induced errors are minimized, and the results can be consistently obtained under the same standards each time.

The invention belongs to the field of oilfield exploitation equipment, particularly relates to a frequency-reducing and anti-attrition reciprocating high-pressure plunger pump, and aims to solve the problems that mechanical abrasion is aggravated and abrasion mechanism qualitative change is caused due to double tests of bearing high-frequency friction and insufficient lubrication between a piston rod and a guide structure during long-time water injection in the prior art; and finally abnormal wear is generated. According to the frequency-reducing and abrasion-reducing type reciprocating high-pressure plunger pump, the multiple parallel plunger units are alternately driven through the crankshaft so that the flow can be equally divided, and the working frequency of the single unit can be reduced; meanwhile, the oil spoon is arranged on the connecting rod, the oil spoon moves along with the connecting rod to splash lubricating oil into the crankcase, and continuous lubrication on moving parts is achieved. Through the mode of combining frequency reduction and load shedding with enhanced lubrication, abrasion aggravation and abrasion mechanism qualitative change are effectively slowed down, the problem of abnormal abrasion is avoided, and the service life of equipment is remarkably prolonged.
