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 zirconium dioxide and up to 20%, more particularly up to 10%, by weight of calcium oxide.

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 μια,' na kterou se musí nejpozději do 5 minut · nanést žárovým stříkáním· · vrstva hliníku ve stejné nebo větší · tloušťce, než · je · tloušťka niklo. vé · · 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 μια, to which an aluminum layer of equal or greater than the nickel thickness must be applied by spraying at the latest within 5 minutes. layer. This protective coating can be used 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. A ochranné povlaky musí plnit především úlohu tepelné clony · a tím snížit tepelné namáhání základního materiálu. Při výrobě ochranných povlaku, je však třeba použít · takovou technologii, · která dovolí nástřik základní · a · ·krycí 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. And the protective coatings must primarily fulfill the function of a heat curtain 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 base coat to be sprayed and the coating layer to be sprayed over a longer time interval than in the known methods.

Nevýhody · stávající ochrany stěn · spalovacíchDisadvantages · existing wall protection · combustion

V7 6 9 8 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 · vápenatého a · zbytek kysličníku zirkoničitého.The V7 6 9 8 chambers provide a 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 of up to 10 weight percent calcium oxide; the rest of the zirconia.

Použitím ochranných · plazmových a žárových nástřiků na tepelně namáhaný materiál, zejména spalovaných 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 ko* mor parních kotlů dojde”k podstatnému snížení pracnosti při výrobě kotlů, úspoře materiálu trnů, úspoře keramického omazu a odstraní se odstavování parních kotlů z důvodu opravy omazu. Odstraněním výpadků kotlů dojde ke zvýšení výkonu energetických bloků. · Snížením tepelné setrvačnosti spalovacích komor je možné dosáhnout · rychlejšího najíždění kotlů na plný výkon.The use of protective plasma and heat spray coatings on thermally stressed material, in particular combustion chambers, results in the formation of satisfactory corrosion protection on the surface of the base material, while effective corrosion protection with plasma or heat spray coatings over a range of operating temperatures ceramic grease several times longer life. The use of the above-mentioned protection of the combustion chamber material of the steam boilers will significantly reduce the work required in the manufacture of boilers, saving the material of mandrels, saving ceramic smearing and eliminating the shutdown of steam boilers due to the repair of smearing. The elimination of boiler failures will increase the output of the power units. · By reducing the thermal inertia of combustion chambers, it is possible to achieve faster start-up of boilers at full output.

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 ochranného povlaku . k cyklickému tepelnému . namáhám, ' zachovám celistvosti a požadovanou žáruvzdornost v atmosféře, 'obsahující sloučeniny síry za teplot převyšujících na povrchu ochranného povlaku 1500 °C.The use of a double-layered protective coating results in thermally activated processes resulting in an increase in the adhesion of the undercoat to the base material due to staying at the working temperature. The results of · long-term tests · showed resistance · double-layer protective coating. to cyclic heat. I try to maintain the integrity and the desired heat resistance in the atmosphere containing sulfur compounds at temperatures in excess of 1500 ° C on the surface of the protective coating.
