Abstract
Description
Invenţia se referă la metodele de obţinere a contactului microfirului şi poate fi utilizată la fabricarea microtermocuplurilor. The invention relates to methods of obtaining microwire contact and can be used in the manufacture of microthermocouples.
Este cunoscut procedeul de obţinere a contactului microfirului în izolaţie de sticlă, care constă în aceea că prin metoda electrochimică pe microfir se depune un metal, care se caracterizează prin proprietăţi termoelectrice ce permit folosirea microfirelor la fabricarea unor termocupluri speciale [1]. The process of obtaining the microwire contact in glass insulation is known, which consists in depositing a metal on the microwire by electrochemical method, which is characterized by thermoelectric properties that allow the use of microwires in the manufacture of special thermocouples [1].
Dezavantajul acestui procedeu constă în aceea că utilizarea ulterioară a microfirelor în izolaţie de sticlă se complică prin lipsa unei bune conexiuni a lor cu colectorul de curent. The disadvantage of this process is that the subsequent use of microwires in glass insulation is complicated by the lack of a good connection between them and the current collector.
Cea mai apropiată soluţie este procedeul de obţinere a contactului microfirului în izolaţie de sticlă de diametru mic (≤10 µm) prin aplicarea amestecului eutectic lichid de In-Ga pe un capăt al microfirului, fixat pe un suport [2]. The closest solution is the process of obtaining the microwire contact in small diameter glass insulation (≤10 µm) by applying the liquid In-Ga eutectic mixture to one end of the microwire, fixed on a support [2].
Dezavantajele procedeului constau în aceea că este limitat de procesul de difuziune a amestecului de In-Ga la temperatura camerei şi nu poate fi asigurat un contact sigur pentru microfirul în izolaţie de sticlă de diametru mic. The disadvantages of the process are that it is limited by the diffusion process of the In-Ga mixture at room temperature and a reliable contact cannot be ensured for the small diameter glass-insulated microwire.
Problema pe care o rezolvă invenţia constă în obţinerea unui contact sigur al microfirului în izolaţie de sticlă de diametru mic, menţinând puritatea microfirului. The problem solved by the invention consists in obtaining a secure contact of the microwire in small diameter glass insulation, maintaining the purity of the microwire.
Procedeul, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că se fixează pe un suport dielectric un microfir în izolaţie de sticlă, se prelucrează preventiv, se depune chimic un strat de metal pe un capăt al microfirului, pe izolaţia de sticlă şi suport, se amplasează suportul cu microfirul în izolaţie de sticlă într-o baie cu electrolit, apoi pe celălalt capăt al microfirului, prin metoda electrochimică cu aplicarea curentului prin impulsuri, se depune un metal. Microfirul, în procesul depunerii electrochimice, este utilizat în calitate de catod, iar în calitate de anod este utilizat un fir din metal, totodată depunerea electrochimică se realizează timp de 18…25 min, cu intensitatea curentului de 1 A/dm2 şi cu perioada dintre impulsuri de 2 s. The process, according to the invention, eliminates the above-mentioned disadvantages by fixing a glass-insulated microwire on a dielectric support, pre-treating it, chemically depositing a metal layer on one end of the microwire, on the glass insulation and support, placing the support with the glass-insulated microwire in an electrolyte bath, then depositing a metal on the other end of the microwire by electrochemical method with pulsed current application. The microwire, in the electrochemical deposition process, is used as a cathode, and a metal wire is used as an anode, while the electrochemical deposition is carried out for 18…25 min, with a current intensity of 1 A/dm2 and a period between pulses of 2 s.
Rezultatul invenţiei constă în asigurarea contactului microfirului în izolaţie de sticlă. The result of the invention consists in ensuring the contact of the microwire in glass insulation.
Exemplu de realizare a procedeului Example of the process
Preliminar depunerii chimice, suprafaţa microfirului în izolaţie de sticlă, fixat pe un suport, s-a prelucrat cu o soluţie de 2% NaOH timp de 2 ore pentru asigurarea rugozităţii suprafeţei de sticlă, după care timp de 2 min s-a prelucrat cu apă distilată cu o temperatură t = 50…60°C . Apoi, timp de 15 min a urmat procesul de sensibilizare într-o soluţie acidă de clorură de staniu cu spălarea ulterioară într-o soluţie slabă de NaOH (pH ~ 9) şi uscarea la aer. A urmat activarea la o temperatură t = 60°C într-o soluţie acidă de clorură de paladiu cu uscarea ulterioară la aer. Pentru depunerea chimică, în particular, a nichelului s-a folosit următorul electrolit, g/l: NiSO4 · 7H2O - 25, NaH2PO2 - 25, Na4P2O7 · 10H2O - 50, pH = 10 - 11 (se adaugă amoniac), t = 65…75°C. Procesul de depunere chimică a decurs timp de o oră, după care a urmat spălarea şi uscarea microfirului în izolaţie de sticlă. După uscare, suportul cu microfirul în izolaţie de sticlă a fost amplasat într-o baie cu electrolit, unde pe celălalt capăt al microfirului, prin metoda electrochimică cu aplicarea curentului prin impulsuri s-a depus un metal, microfirul, în procesul depunerii electrochimice, fiind utilizat în calitate de catod, iar în calitate de anod fiind utilizat un fir din metal, totodată depunerea electrochimică a fost realizată timp de 18…25 min, cu intensitatea curentului de 1 A/dm2 şi cu perioada dintre impulsuri de 2 s. Prior to chemical deposition, the surface of the glass-insulated microwire, fixed on a support, was treated with a 2% NaOH solution for 2 hours to ensure the roughness of the glass surface, after which it was treated with distilled water at a temperature of t = 50…60°C for 2 min. Then, for 15 min, the sensitization process in an acidic solution of tin chloride followed by washing in a weak solution of NaOH (pH ~ 9) and air drying. Activation at a temperature of t = 60°C in an acidic solution of palladium chloride followed by air drying. For chemical deposition, in particular, of nickel, the following electrolyte was used, g/l: NiSO4 · 7H2O - 25, NaH2PO2 - 25, Na4P2O7 · 10H2O - 50, pH = 10 - 11 (ammonia is added), t = 65…75°C. The chemical deposition process lasted for one hour, after which the microfiber in glass insulation was washed and dried. After drying, the support with the glass-insulated microwire was placed in an electrolyte bath, where a metal was deposited on the other end of the microwire, by the electrochemical method with the application of pulsed current, the microwire, in the electrochemical deposition process, being used as a cathode, and a metal wire being used as an anode, at the same time the electrochemical deposition was carried out for 18…25 min, with a current intensity of 1 A/dm2 and a period between pulses of 2 s.
Astfel, procedeul elaborat permite obţinerea contactului microfirului în izolaţie de sticlă, fapt ce poate fi utilizat la fabricarea microtermocuplurilor. Thus, the developed process allows obtaining microwire contact in glass insulation, which can be used in the manufacture of microthermocouples.
