Provided is a cooker which has a frame forming a side plate, which can be easily manufactured and can reduce manufacturing cost. The cooker includes a cooktop assembly for cooking and directly heating a container in which food is accommodated. The cooktop assembly includes a side plate having at least two frames coupled to each other, and a top plate located at an upper portion of the side plate.

An airfoil surface includes a first titanium portion, a second titanium portion, an aluminum alloy braze disposed there between, and a titanium coating covering the aluminum alloy braze, at least part of the first titanium portion and at least part of the second titanium portion.

Methods for preparing an environmental barrier coating and the resulting coating are provided. The methods and products include the incorporation of a continuous ceramic inner layer and a segmented ceramic outer layer on a CMC component. The segmented ceramic outer layer may be formed by thermal spray techniques. The coating is more stable at higher temperatures and provides for a longer lifetime of the coated component.

A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

Method for producing a metal coated steel substrate provided with a coating of a primer composition, comprising applying a layer of the primer composition on the metal coated steel substrate wherein the primer composition comprises basic components selected from the group consisting of CuO, K.sub.20, Li.sub.20, Na.sub.20, Ce0.sub.2 and ZnO; components with intermediate acidity selected from the group consisting of Al.sub.20.sub.3, B.sub.20.sub.3, Cr.sub.20.sub.3, Sn0.sub.2 Sb.sub.20.sub.3 and Fe.sub.20.sub.3; acidic components selected from the group consisting of Mn0.sub.2, Mo0.sub.3, P.sub.20.sub.5, Si0.sub.2, Ti0.sub.2, V.sub.20.sub.5, W0.sub.3 and Zr0.sub.2; wherein all wt. % are drawn on the total primer composition and the total sum of the amounts excluding impurities and after normalization is 100 wt. %, wherein all components are expressed as oxides, wherein the sum of the amounts of Ce0.sub.2+Cr.sub.20.sub.3+CuO+Fe.sub.20.sub.3+Mn0.sub.2+Mo0.sub.3+Sn0.sub.2+Sb.sub.20.sub.3+V.sub.20.sub.5 W0.sub.3 is between about 16.7 and about 48.6 wt. %.

A fired hybrid enamel coating is provided. The hybrid enamel coating is formed by firing an enamel composition on a substrate. The enamel composition includes at least a first glass frit, which is sintered to form the hybrid enamel coating. The hybrid enamel coating can be cleaned using aqualytic or pyrolytic cleaning methods, and does not discolor or lose gloss when subject to typical pyrolytic cleaning methods. The hybrid enamel coating does not require the application of highly caustic cleaners to remove the baked-on soils
