摘要：

Nickel　and　tungsten　composite　coatings　were　prepared　by　molten　salt　electrodeposition.　Micromorphology,　grain　size　and　ratio　of　low　angle　grain　boundaries　of　the　coatings　were　characterized　by　means　of　scanning　electronic　microscopy　(SEM)　and　electron　backscattered　diffraction　(EBSD)　technique.　The　results　show　that　the　surface　of　coatings　prepared　at　current　of　70~100　mA/cm2　is　smooth　and　compact.　Fracture　mechanism　of　the　Ni/W　coatings　is　cleavage　fracture.　Thickness　of　the　coatings　increases　with　the　increasing　current　density.　Grain　size　and　ratio　of　low　angle　grain　boundaries　of　the　coatings　decrease　with　the　increasing　current　density,　and　this　is　beneficial　to　obtaining　the　high　performance　of　the　coatings.　©　2016,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
