Invenția se referă la un procedeu de acoperire a suprafețelor de contact ale corpurilor care au mișcări relative între ele prin depunerea pe aceeași suprafață a mai multor straturi de material, pentru a răspunde cerințelor de a asigura proprietățile tribologice, mecanice, termice, estetice, chimice, precum și de protecție anticorozivă și biologică a acestora.The invention refers to a method of covering the contact surfaces of bodies that have relative movements between them by depositing several layers of material on the same surface, in order to meet the requirements to ensure the tribological, mechanical, thermal, aesthetic, chemical, as well as their anticorrosive and biological protection.
Este cunoscută realizarea prin galvanizare a unor straturi întrepătrunse, care este posibilă prin acoperirea suprafețelor piesei care dorim să rămână neacoperită după operația de galvanizare cu materiale fără conductivitate electrică.It is known to achieve interpenetrated layers by galvanizing, which is possible by covering the surfaces of the part that we want to remain uncovered after the galvanizing operation with materials without electrical conductivity.
Pulverizarea termică este un alt procedeu care răspunde cerințelor de realizare a invenției, fie în mod direct prin depunerea întrepătrunsă a straturilor, fie prin prelucrarea straturilor depuse în vederea realizării unui spațiu în care să se depună noi straturi. Uneori, depunerea de straturi suprapuse sau întrepătrunse poate fi urmată de încălzirea corpului. Prin aceasta se realizează mărirea grăunților și crearea de punți care să închidă microfisurile și totodată să favorizeze difuzia straturilor: în materialul de bază și/sau între straturile depuse contribuind la îmbunătățirea aderenței.Thermal spraying is another process that meets the requirements for the realization of the invention, either directly by interpenetrating the layers, or by processing the deposited layers in order to create a space in which to deposit new layers. Sometimes the deposition of overlapping or interpenetrating layers may be followed by heating of the body. By doing this, the grains are enlarged and bridges are created to close the microcracks and at the same time favor the diffusion of the layers: in the base material and/or between the deposited layers contributing to the improvement of adhesion.
Pulverizarea termică este o tehnologie de modificare a suprafeței în care metalele și ceramica sunt încălzite la o stare topită sau semi-topită și apoi sunt făcute să se ciocnească și să se acumuleaze pe suprafața unui substrat formând astfel o acoperire. Principalii parametrii ai procesului care influențează aderența stratului față de materialul de bază sunt temperatura care topește materialul de adaus si viteza de impact a particulelor topite.Thermal spraying is a surface modification technology in which metals and ceramics are heated to a molten or semi-molten state and then collided and deposited on the surface of a substrate to form a coating. The main process parameters that influence the adhesion of the layer to the base material are the temperature that melts the additive material and the impact speed of the melted particles.
Dintre procedeele de pulverizare termică se distinge procedeul High Velocity Oxigen Fuel (HVOF), caracterizat prin obținerea unei temperaturi ridicate ca urmare a arderii într-o camera internă de combustie a unui unui amestec de hidrocarburi cu hidrogen și prin convertirea acestuia întrun jet de gaze de combustie de temperatură ridicată și cu viteză supersonică de 5 mach si mai mare. Gazele de combustie sunt eliberate prin duze iar prin mijlocul lor este aspirat materialul de adaus sub forma de pudră care este topită și încorporată în jetul de gaze foarte focalizat, ceea ce permite depunerea unor straturi înguste și aderente.Among the thermal spraying processes, the High Velocity Oxygen Fuel (HVOF) process is distinguished, characterized by obtaining a high temperature as a result of the combustion in an internal combustion chamber of a mixture of hydrocarbons with hydrogen and by converting it into a jet of gases high temperature combustion and supersonic speed of mach 5 and higher. Combustion gases are released through the nozzles and through them the additive material is sucked in the form of powder which is melted and embedded in the highly focused gas jet, which allows the deposition of narrow and adherent layers.
Activitățile cu privire la fenomenele care au loc pe suprafețele corpurilor aflate in contact si au o mișcare relativa între ele se refera la modalitățile prin care se pot reduce: abraziunea, adeziunea, eroziunea (particule solide sau cavitație), frecarea, impactul, fretingul, uzura și contactul cu suprafețele dure. Acești factori sunt influențați direct de alegerea materialului, de acoperire a suprafețelor și de topografia acestora.The activities regarding the phenomena that take place on the surfaces of the bodies in contact and have a relative movement between them refer to the ways in which they can be reduced: abrasion, adhesion, erosion (solid particles or cavitation), friction, impact, fretting, wear and contact with hard surfaces. These factors are directly influenced by the choice of material, surface coverage and topography.
Prin documentul JPH 01240677 (A)/(1989), este cunoscut un procedeu de acoperire a unui metal cu un strat rezistent la coroziune , realizat prin activarea suprafeței unui metal de bază cum ar fi oțelul sau Al, depunerea unui strat de placare rezistent la coroziune din Ni, etc., având o grosime de aproximativ 5 pm-5 mm, format pe suprafața activată prin electroplacare sau altă metodă de placare și pulverizarea termică pe acesta a unor particule fine de material, cu plasmă sau gaz pentru a forma straturi pulverizate care sunt, de preferință, un strat de acoperire din Mo sau un aliaj Ni-Co pentru îmbunătățirea aderenței și un strat de strat superior de alumină sau titan, de înaltă duritate.Through document JPH 01240677 (A)/(1989), a method of covering a metal with a corrosion-resistant layer is known, achieved by activating the surface of a base metal such as steel or Al, depositing a plating layer resistant to corrosion of Ni, etc., having a thickness of about 5 pm-5 mm, formed on the activated surface by electroplating or other plating method and thermal spraying on it of fine particles of material, with plasma or gas to form sprayed layers which are preferably a coating of Mo or a Ni-Co alloy to improve adhesion and a high-hardness alumina or titanium topcoat layer.
De asemenea, documentul JPS 5896862 (A)/1983 prezintă un procedeu de obținere a unei acoperiri compozite a unei plăci de oțel, rezistentă la coroziune, căldură, abraziune și oxidare, prin formarea de pelicule ceramice pe o peliculă metalică, în combinațiile utile permise de tehnicile de pulverizare termică și laminare, un prim strat pulverizat de metal topit fiind depus pe o lamelă laminată, de exemplu, pe o placă iar un strat de ceramică pulverizat în topitură este depus suprapus peste aceasta, o altă placă fiind apoi suprapusă pe ea, astfel încât să acopere straturile anterioare, după care lamelele suprapuse sunt înmuiate la o temperatură de laminare la cald, pentru a accelera difuzarea stratului la placă și înmuierea stratului și apoi sunt laminate la cald, la finalizarea laminării, placa laminată având straturile de acoperire compozite fiind separată de cealaltă placă.Also, document JPS 5896862 (A)/1983 presents a process for obtaining a composite coating of a steel plate, resistant to corrosion, heat, abrasion and oxidation, by forming ceramic films on a metal film, in the useful combinations allowed by thermal spray and lamination techniques, a first sprayed layer of molten metal being deposited on a laminated lamella, for example, a plate and a ceramic layer sprayed in the melt is deposited superimposed on this, another plate being then superimposed on it , so as to cover the previous layers, after which the overlapping laminae are soaked at a hot rolling temperature to accelerate the diffusion of the layer to the plate and the softening of the layer, and then they are hot rolled, at the completion of the lamination, the laminated plate having the composite coating layers being separated from the other board.

Problema tehnică pe care o rezolvă invenția constă în realizarea unei acoperiri anticorozive tip multistrat a unei piese metalice care să aibă o bună aderență la substrat și să 17 fie rezistentă la uzura de frecare prin contact cu alte piese.The technical problem that the invention solves consists in creating a multi-layer anti-corrosion coating of a metal part that has good adhesion to the substrate and is resistant to frictional wear through contact with other parts.
Procedeul de realizare a unei acoperiri anticorozive tip multistrat pentru protecția unei 19 piese metalice, rezistentă la uzura de frecare, rezolvă această problemă tehnică prin aceea că este realizat prin fazele de acoperire a suprafeței de contact a unui corp metalic prin 21 depunerea pe aceeași suprafață a mai multor straturi de material de protecție anticorozivă, care au compoziții diferite, prin galvanizare, sau/și prin pulverizare termică, depunerea 23 straturilor de protecție anticorozivă fiind realizată astfel încât acestea să fie întrepătrunse, de tip strat lângă strat, ca un mozaic și variabil distribuite, prin acoperirea suprafețelor piesei 25 care trebuie să rămână neacoperite după operația de galvanizare cu materiale fără conductivitate electrică în cazul depunerii prin galvanizare și/sau prin prelucrarea primelor straturi 27 depuse prin pulverizare termică sau galvanizare în vederea realizării unui spațiu în care sunt depuse ulterior noi straturi. 29The process of making a multi-layer anti-corrosion coating for the protection of a metal part, resistant to frictional wear, solves this technical problem in that it is made through the phases of coating the contact surface of a metal body by depositing on the same surface several layers of anti-corrosion protection material, which have different compositions, by galvanizing, and/or by thermal spraying, the deposition of the 23 anti-corrosion protection layers being carried out so that they are interpenetrated, layer by layer, like a mosaic and variable distributed, by covering the surfaces of the piece 25 that must remain uncovered after the galvanization operation with materials without electrical conductivity in the case of deposition by galvanization and/or by processing the first layers 27 deposited by thermal spraying or galvanization in order to create a space in which they are subsequently deposited new layers. 29
