Self-repairing principle: Friction and wear are performed simultaneously on the two friction surfaces of the friction pair. Under the action of ultra-high temperature and ultra-high pressure on the local contact point of the friction surface, the repair agent particles act as a catalyst to bring the metal particles in the lubricating oil back to the surface wear site with higher surface activity. It produces the most energy in the highly worn low recesses. This motivates the return of the metal particles and self-repairing in the low recesses.
The metal particles returned to the friction surface have greater surface activity, capturing carbon and oxygen atoms that are decomposed in the lubricant due to frictional heat. Therefore, this forms a diamond-like structural repair layer on the friction surface that is indistinguishable from the composition of the original substrate. As the repair layer is formed, the wear between the friction surfaces drops sharply, and the energy required to activate the repair agent is correspondingly reduced.
When the gap of the friction pair surface tends to be optimal, the self-repair process gradually tends to stop. At this time, the friction pair changes from "between metal and metal" to "between metal repair layer and metal repair layer". Since the repair layer formed on both surfaces of the friction pair is similar in hardness and extremely high in hardness and has extremely low roughness, which brings it with excellent antifriction and antiwear properties.
Characteristics and indicators of "VANS TECH" military-
grade precision metal wear-resisting technology.
The surface microhardness of"VANS TECH" metal repair layer is 1 to 3 times higher than that of the original substrate surface. The microhardness can reach above HV800, and the nano hardness can reach above 10GPa.
"VANS TECH" military-grade precision metal wear-resistant repair technology can repair the natural wear-resistant wounds or groove marks up to 200սm deep, so that it can restore the original size and fit clearance.
The surface roughness of"VANS TECH" metal repair layer reaches Ra=0.008սm, which is an extremely smooth mirror surface.
The friction coefficient of"VANS TECH" metal repair layer is less than 0.01, which is an order of magnitude lower than the boundary oil film lubrication. This can improve the antifriction and antiwear effect of the friction pair surface.
"VANS TECH"metal repair layer forms a metal bond with the original base metal surface, and is formed from the inside to the outside on the worn surface without a distinct interface. This is different from other coating techniques that are generated or plated outward along the metal surface. Therefore, "VANS TECH" metal repair layer does not change the original original size of the component, and does not peel or fall off, but automatically and selectively compensates for the repaired wear surface. Optimize the fit clearance of the components. The thickness of the repair layer is proportional to the energy produced by the friction. This means that the original dimensions of the friction pair components can be maintained and the optimum fit clearance is achieved.
"VANS TECH"metal repair layer has higher hardness, thermal stability, thermal shock resistance, abrasion resistance and corrosion resistance than the original metal surface. The outstanding feature of"VANS TECH" self-repair process is its self-regulating repair ability. It is attributed to the special formula and efficacy of "VANS TECH" repair agent. The repair agent plays a key role in the formation and growth of the metal repair layer.
Self-repair is performed simultaneously on the friction surfaces of the friction pair during friction and wear. With the formation of a diamond-like metal repair layer, the friction coefficient between the friction surfaces drops sharply, and the frictional capacity required to activate the repair agent is greatly reduced. When the friction pair fits the gap, the self-repair process gradually becomes stable. That is to achieve the dynamic balance of one side wear and repair. Since the metal repair layer formed on both surfaces of the friction pair has extremely high hardness and extremely low surface roughness, this greatly improves the frictional performance of the friction pair surface. This brings excellent anti-friction and anti-wear properties.
Self-repair is performed simultaneously on the friction surfaces of the friction pair during friction and wear. With the formation of a diamond-like metal repair layer, the friction coefficient between the friction surfaces drops sharply, and the frictional capacity required to activate the repair agent is greatly reduced. Partial repair layer wear caused by long-term operation can be reconstructed by adding “VANS TECH” friction surface repair agent again. This can bring the mechanical equipment with the lifetime dismantling maintenance.
Friction and wear test data
The comparison of friction and wear experimental data of "VANS TECH" military-grade precision metal wear-resistant repair technology with other brand products.
The friction and wear evaluation of “VANS TECH” self-repairing agent was carried out on the GWL1000 pin-slot test machine.
The sample above is a fixed 45# steel with a hardness of HV450, which is in line contact with the sample below; the sample below is a disk that rotates with the axis. Material 45# steel, hardness HV221, surface roughness Ra = 0.8 μm.
In the test, L-AN 46# mechanical oil was used as the base oil, and the additives used were other brand repairing agents and VANS TECH repairing agents. The concentration was 0.8% (volume percent); the number of revolutions was 600 rpm, using step loading; a total of 60 hours of testing.
The following figure shows the friction and wear test results of L-AN 46# mechanical oil, other brand repair agents and VANS TECH repair agent. It can be seen that the anti-friction and anti-wear effect of VANS TECH repair agent is obviously better than other brands。
