| Abstract: | According to the actual condition of belt conveyers' bucket padding plate machine spare parts, submerged arc of dot shaped hard facing process are applied. Reasonable process parameters are defined, increasing productivity, prolonging service life of bucket padding plate and reducing costs. The results show that hard facing layer have high hardness, anti wear performance and suitability. This process can be used as surface strengthening of machine spare parts. |
