Abstract

A protective coating for heat stressed parts, particularly firing chambers of steam boilers, comprises a first, base, layer and a second, upper, layer. The base layer comprises nickel and 10 to 30% by weight of chromium and the upper layer comprises aluminium oxide and up to 20%, more particularly up to 10%, by weight of titanium dioxide.

Description

Vynález řeší ochranné povlaky pro použití při ochraně tepelně namáhaných součástí, zejména spalovacích komor parních kotlů plazmovým nebo žárovým nástřikem.The invention solves protective coatings for use in the protection of thermally stressed components, in particular combustion chambers of steam boilers by plasma or heat spraying.

Pro zajištění ochrany stěn spalovacích komor parních kotlů proti korozi jsou na kotlové trubky navařovány trny z nerezavějící oceli, na kterých je keramický omaz. Uvedený způsob ochrany je velice pracný a předpokládá obnovu keramického omazu v pravidelných cyklech.In order to protect the walls of the combustion chambers of the steam boilers against corrosion, stainless steel mandrels are welded onto the boiler tubes on which the ceramic coating is applied. Said method of protection is very laborious and assumes the renewal of ceramic smearing in regular cycles.

Jedním ze známých způsobů ochrany ocelových součástí je podle čs. patentu č. 130001 žárový nástřik vrstvy niklu v tloušťce 50 až 200 μπι, na kterou se musí : nej později do 5 minut nanést žárovým stříkáním vrstva hliníku ve stejné nebo větší tloušťce, než je tloušťka niklové vrstvy. Tento ochranný povlak je použitelný do teploty 1200 °C na vzduchu a v atmosféře obsahující sloučeniny síry.One of the known methods of protection of steel parts is according to MS. No. 130001, a thermal spray of a nickel layer of 50 to 200 μπι, to which an aluminum layer of at least the same thickness as the nickel layer must be applied by hot spraying at the latest within 5 minutes. This protective coating is applicable up to 1200 ° C in air and in an atmosphere containing sulfur compounds.

Pro ochranu kotlových trubek je třeba uvažovat s povlaky, které jsou namáhány vyššími teplotami, než je teplota tavení strusky, která stéká po stěnách spalovacích komor. Ochranné povlaky musí plnit především úlohu tepelné clony a tím snížit tepelné namáhání základního materiálu. Při výrobě ochranných povlaků je však třeba použít takovou technologii, která dovolí nástřik základní a krýcí vrstvy s větším časovým odstupem, než u známých způsobů.In order to protect the boiler pipes, it is necessary to consider coatings subjected to higher temperatures than the melting temperature of the slag which flows down the walls of the combustion chambers. Protective coatings must primarily fulfill the function of a thermal screen and thus reduce the thermal stress of the base material. However, in the manufacture of protective coatings, it is necessary to use a technology which allows the spraying of the base and covering layers over a longer period of time than in the known methods.

Nevýhody stávající ochrany stěn spalovacích komor řeší dvouvrstvý ochranný povlak, podle vynálezu, který obsahuje v první vrstvě 70 až 90 hmotnostních procent niklu a 10 až 30 hmotnostních procent chrómu, v podstatě tím, že druhá vrstva obsahuje stopy až 10 hmotnostních procent kysličníku titaničitého a zbytek kysličníku hlinitého.Disadvantages of the existing combustion chamber wall protection are solved by the two-layer protective coating according to the invention, which contains 70 to 90 weight percent nickel and 10 to 30 weight percent chromium in the first layer, essentially in that the second layer contains traces up to 10 weight percent titanium dioxide and of aluminum oxide.

Použitím ochranných plazmových a žárových nástřiků na tepelně namáhaný materiál, zejména spalovacích komor, dojde k vytvoření vyhovující korozní ochrany na povrchu základního materiálu, přičemž účinná korozní ochrana plazmovým nebo žárovým nástřikem má v rozsahu pracovních teplot ve srovnání s keramickým omazem několikanásobně větší životnost. Použitím uvedené ochrany materiálu spalovacích komor parních kotlů dojde k podstatnému snížení pracnosti při výrobě kotlů, úspoře materiálu trnů, úspoře keramického omazu a odstraní se odstavování parních kotlů z důvodů opravy omazu. Odstraněním výpadků kotlů dojde ke zvýšení výkonu energetických bloků. Snížením tepelné setrvačnosti spalovacích komor je možné dosáhnout rychlejšího najíždění kotlů na plny výkon.The use of protective plasma and heat spray coatings on thermally stressed material, in particular combustion chambers, results in satisfactory corrosion protection on the surface of the base material, while effective corrosion protection by plasma or heat spraying has a several times longer service life compared to ceramic coating. The use of said material protection of the combustion chambers of steam boilers will significantly reduce the workmanship in the manufacture of boilers, saving the material of mandrels, saving ceramic lubrication and eliminating the shutdown of steam boilers due to the repair of the lubrication. The elimination of boiler failures will increase the output of the power units. By reducing the thermal inertia of the combustion chambers, it is possible to achieve faster start-up of boilers to full capacity.

Použitím dvouvrstvého ochranného povlaku dojde v důsledku setrvání na pracovní teplotě k tepelně aktivovaným dějům, které mají za následek zvýšení přilnavosti podkladové vrstvy k základnímu materiálu. Výsledky dlouhodobých zkoušek prokázaly odolnost dvouvrstvého povlaku к cyklickému tepelnému namáhání, zachování celistvosti a požadovanou žáruvzdornost v atmosféře obsahující sloučeniny síry za teplot převyšujících na povrchu ochranného povlaku 1500 °C.The use of a two-layer protective coating results in thermally activated processes resulting in an increase in the adhesion of the base layer to the base material as a result of staying at the working temperature. The results of long-term tests have shown the resistance of the two-layer coating to cyclic thermal stress, integrity and the required heat resistance in an atmosphere containing sulfur compounds at temperatures in excess of 1500 ° C on the surface of the protective coating.

Podkladová vrstva v tloušťce 0,17 mm je tvořena nástřikem, který obsahuje . ..........An example of the use of the protection of thermally stressed materials of combustion chambers of steam boilers is the plasma spraying of tubes surface-roughened by blasting of 52 mm wall thickness of 4 mm steam boiler. The backing layer at a thickness of 0.17 mm is formed by a spray which it contains. ..........

kromě niklu 20,2 hmotnostních procent chrómu. Krycí vrstva v tloušťce 0,45 až 0,60 mm obsahuje kromě kysličníku hlinitého 13,6 hmotnostních procent kysličníku titanicitého.in addition to nickel, 20.2 weight percent chromium. In addition to aluminum oxide, the covering layer 0.45 to 0.60 mm thick contains 13.6 weight percent titanium dioxide.

Příklad 2Example 2

Obdobným příkladem je plazmový nástřik trubek rovněž parního kotle. Na trubky zdrsněné tryskáním 0 76 mm tloušťky stěny 5 mm byla nastříkána podkladová vrstva v tloušťce 0,09 mm obsahující kromě niklu 15,8 hmotnostních procent chrómu. Krycí vrstva obsahovala kromě kysličníku hlinitého 5,8 hmotnostních procent kysličníku titaničitého a dosahovala tloušťky 0,43 až 0,70 mm.A similar example is the plasma spraying of steam boiler tubes. An underlay of 0.09 mm thickness containing 15.8 percent by weight of chromium in addition to nickel was sprayed onto the pipes blasted with 0 76 mm wall thickness of 5 mm. The cover layer contained, in addition to alumina, 5.8 weight percent of titanium dioxide and reached a thickness of 0.43-0.70 mm.
