The invention discloses an alloy laser-cladding method for the surface of a helical casing in a screw pump. In the method, high temperature-resistant, corrosion-resistant and abrasion-resistant alloy powder is cladded on the surface of a helical casing by using the laser technology, thus forming an alloy cladding layer. The alloy powder contains elements or oxides thereof which are capable of refining, intensifying and having other effects on crystal grains of the alloy cladding layer, so the structural characteristics of the alloy cladding layer appears as refining of the crystal grains, increase of the dislocation density and uniform and compact structure, and the alloy cladding layer also has the effects on solution strengthening of the supersaturated alloy, and dispersion strengthening of superfine compounds and the like. Thus, the rigidity, wear resistance, corrosion resistance, fatigue resistance and other mechanical properties of the surface of the helical casing can be effectively ...

The invention relates to the technical field of tile paving, in particular to a tile elevation positioner. The invention provides a ceramic tile elevation positioner capable of marking in two directions at the same time. A ceramic tile elevation positioner comprises a positioning frame, a lifting mechanism and a marking mechanism, the positioning frame is arranged on the ground, the marking mechanism used for marking the paving position of a ceramic tile is arranged on the positioning frame, and the lifting mechanism used for adjusting the height of the marking mechanism is arranged on the positioning frame. A gear set rotates to drive a supporting plate, a first supporting frame and a first carving block to move up and down, the first carving block moves left and right to mark a wall face in the horizontal direction, accordingly, ceramic tiles are positioned, and the effect of improving the ceramic tile paving efficiency is achieved.

Method for cladding alloy on the surface of steel injection plunger

Номер: CN0101586238B
Автор: LANG JUAN, FENG JIAWANG, SU JIANQUAN, CHEN DONGZHANG, JUAN LANG, JIAWANG FENG, JIANQUAN SU, DONGZHANG CHEN

The present invention discloses a method for cladding alloy on the surface of steel injection plunger. The method uses laser technology for cladding the high temperature resistant and abrasion-resistant alloy powder on the surface of the steel injection plunger for forming one layer of alloy cladding layer. As the alloy power contains the elements with the functions of grain refinement, grain strengthening, etc. for the alloy cladding layer or the oxides of the elements, the alloy cladding layer has the tissue characteristics of refined grain, increased dislocation density, uniform and compacttissue. Simultaneously the alloy cladding layer has the solid solution strengthening function of the super-saturated alloy and the dispersion strengthening function of the ultra-fine compound, etc.,therefore the surface strength of the steel injection plunger can be effectively increased thereby preventing the cracking or surface strain caused by thermal fatigue. Additionally, the alloy claddinglayer ...
