ResultsandDiscussion

Theresultsoftheexperimentsshowedthattheiron-basedamorphouscoatingsdisplayedexcellentwearresistanceunderdryabrasiveconditions.Thewearratewasfoundtodecreaseasthesizeoftheabrasiveparticlesincreased,indicatingthatlargerparticleswerelesseffectiveatcausingwearinthecoating.Thecoefficientoffrictionalsodecreasedwithincreasingparticlesize,suggestingthatlargerparticlesleadtosmootherslidingbetweentheabrasiveandthecoating.

Underwetabrasiveconditions,thewearrateoftheiron-basedamorphouscoatingsincreasedsignificantly,duetothelubricatingeffectofthewater.However,thecoatingstillexhibitedbetterwearresistancecomparedtoothermaterialssuchasstainlesssteel.Thepresenceofwaterwasalsofoundtoincreasethecoefficientoffriction,whichcanleadtoanincreaseinenergyconsumptionduringoperation.
