The　amount　of　borocarbide　in　high-boron　low-carbon　ferro-matrix　alloy　with　0.5%-3.0%　B　and　0.4%　C　had　been　analyzed　after　quenched　at　1000°C　for　2　h　and　tempered　at　200°C　for　4　h　using　the　Leica　Qwin　image　analysis　system.　The　wear　resistance　of　the　alloy　was　measured　using　the　ML-10　type　two-body　pin-on-disc　wear　tester　and　MLD-10　type　three-body　impact　wear　tester,　respectively.　The　results　showed　that　the　effect　of　boron　content　on　the　volume　fraction　of　borocarbide　is　in　accord　with　the　exponential　curve,　namely,　y=7.078　e　0822x.　Under　the　condition　of　two-body　wearing,　the　wear　resistance　of　the　high-boron　low-carbon　ferro-matrix　alloy　is　better　than　that　of　high　chromium　cast　iron　and　increases　with　the　increase　of　boron　content.　Under　the　three-body　impact　wearing　condition,　the　wear　resistance,　for　the　alloy　with　B　less　than　1.5%,　is　higher,　but　slightly　lower,　for　the　alloy　with　B　greater　than　1.5%,　than　that　of　high　chromium　cast　iron.
