The research results show that, from the viewpoint of second phase morphologies, there exist quite differences between the grain - type materials ( such as wc / bcu brazing deposit material, wrs1000 and 1zt tungsten carbide strengthening overlaying material, as well as the wear - resistant material of polymer adhesive coating etc. ), and the aggregation - type as well as dispersion - type ones ( such as zg35simn, wrd - 1 and khc - k2 depositing material ) in the wear - resistance and sand slurry abrasion mechanism. the sand slurry abrasion mechanisms are brought forward, of new wear - resistant materials with the features of grain - type second phase morphologies
研究發現,與聚合型、彌散型第二相的材料(如zg35simn 、 wrd ? 1和khc ? k2熔敷材料等)相比,顆粒型第二相的材料(如wc bcu釬焊熔敷耐磨材料、 wrs1000型耐磨材料、 1zt碳化鎢顆粒增強熔敷材料及ktc ? 1耐磨膠粘塗層材料等)在耐磨性能和磨損機理等方面均有不同,總結提出了以「顆粒型第二相」為特徵的耐磨新材料泥沙磨損機理。Meanwhile it retains evenness on lift force to prevent leakage of residue that is caused by installation clearance error or changes in welding criteria, flow off molten iron as well as break - over welding, so that the ideal fosion depth and finishment have been fulfilled
在需原動力的條件下,該機利用彈性夾角變化,隨著筒體轉動,使墊層焊劑始終緊貼筒體外側環向焊接區,並保持托力均勻防止因裝配間隙誤差或焊接規范變化而引起漏渣,鐵水下淌及焊穿現象,達到理想的熔深度和光潔度。Effect of wc addition on erosion - wear behavior of fused ni60 alloy self - fluxing coating
60自熔合金噴焊層沖蝕磨損特性的影響Each pass shall be cleaned free of slag before the next pass is deposited. each weld layer shall be visually free of slag inclusions, cracks, porosity and lack of fusion
每一層焊道都應在熔敷下一層焊道前清除熔渣。每一焊層都不得有可見的夾渣、裂紋、氣孔及未熔透現象。The maximal power outputs of 37. 0 mw / cm2 and 30. 0 mw / cm2 for the p - and n - type laminated materials respectively at the temperature difference 490 have been experimentally obtained, which are about 2. 5 and 3. 0 times those of - fesi2. chemical analyses show that the interface failure between the bridge alloy and the semiconductor bi2te3 results mainly from the eutectic mixtures with low melting point and brittle compounds formed during welding and long time annealing at 190. it is found that the electrical properties of a laminated structure are mainly controlled by the wettability of the bridge alloy on the semiconductor surface
發現: 1 )疊層材料具有明顯優于均質材料的熱電性能,在490溫差下, p -型和n -型疊層材料的最大輸出功率分別達到37 . 0和30 . 0 ( mw / cm ~ 2 ) ,是同類型均質- fesi _ 2的2 . 5和3倍; 2 )在焊接過程和190長時間退火處理過程中,焊接過渡層合金和基體半導體(特別是bi _ 2te _ 3 )之間存在明顯的元素相互擴散,從而在過渡層中形成一些低熔點共晶體和脆性化合物,這是導致疊層材料破壞的主要原因; 3 )焊接過渡層合金與半導體基體之間的潤濕性是影響界面層電性能的主要因素。The deposited ferritic weld metal shall not contact the austenitic or high - chromium steel cladding
熔敷的鐵素體焊縫金屬不應與奧氏體或高鉻鋼復層接觸。With the induction depositing process especially, as well as the overlaying deposit and the adhesive coating process for wear resistance, in consideration of the material manufacture and application, some types of new wear - resistant materials, including metallic materials, their composites and polymers are designed and developed. the research results on wear - resistant properties, microstructures and worn morphologies show that these materials possess their own characteristics, present the excellent and synthetic properties
