【摘 要】The amorphous Ni-P coatings (10.90 wt. % ) were deposited on

carbon steel by electroless method, furthermore, the effect of as-deposits

structure, properties and heat-treatment temperture on the corrsion

resistance were investigated. The results show that the corrsion resistance

of amorphous Ni-P coatings is superior in 10% HC1 soultion. The corrsion

resistance is affected by heat treatment, as the performance of corrsion

resistance has improved 37% after amorphous Ni-P coatings heated at

2001. Additionally, metasta-ble and stable phases are presented in Ni-P

coatings as the temperature reaches at 300 and 400℃ respectively,

however, the corrsion resistance is reduced, which is still higher than as-deposited Ni-P coatings.%采用化学镀方法在碳钢上沉积非晶Ni-P合金镀层(10.90wt.%),考察Ni-P合金结构、性能及热处理温度对耐蚀性的影响.结果表明:在10% HCl溶液中,非晶Ni-P镀层具有较好的耐蚀性;热处理影响镀层的耐蚀性,非晶Ni-P镀层经200℃热处理后,可使耐蚀性能提高37%,热处理温度达到300℃和400℃时,镀层分别出现亚稳相和稳定相,耐蚀性能降低,但耐蚀性仍优于镀态Ni-P镀层.
