Hypereutectic　High　Chromium　Cast　Iron　(HHCCI)　is　a　new　type　of　corrosion-wear-resistant　material　developed　from　ordinary　high　chromium　cast　iron　by　increasing　the　chromium　and　carbon　content　and　is　often　used　in　abrasive　environments　where　wear　and　corrosion　interact.　The　corrosion　wear　resistance　of　the　HHCCI　is　related　to　the　number,　size,　shape　and　distribution　of　carbides　and　the　microstructure　of　the　matrix.　This　paper　reviews　the　research　progress　in　improving　the　corrosion　wear　resistance　of　HHCCI　from　various　aspects　such　as　primary　carbide　refinement,　heat　treatment,　deep　cooling　treatment　and　alloying,　etc.　Among　the　methods　of　refining　primary　carbides　are　modification,　semi-solid　treatment　and　current　pulse　treatment.　In　addition,　we　also　analyze　the　potential　of　Cr,　V,　Nb,　Mo,　Mn,　W,　Ni,　Cu,　Si,　N　and　other　alloying　elements　to　improve　the　corrosion　wear　resistance　of　HHCCI.　The　mechanism　for　improving　the　corrosion　wear　resistance　of　HHCCI　is　also　explored　in　depth　and　research　contents　worthy　of　attention　are　proposed　to　further　improve　the　corrosion　wear　resistance　of　HHCCI.　In　the　future,　the　author　believes　that　modification　+　alloying　+　heat　treatment　is　the　most　potential　application　method　to　improve　the　corrosion　wear　resistance　of　HHCCI.　The　corrosion　wear　resistance　of　HHCCI　can　be　further　improved　by　refining　the　primary　carbide　(such　as　adding　rare　earth,　Ti　and　other　modified　elements)　+　heat　treatment　(with　cryogenic　treatment)　to　improve　the　strength　+　alloying　(such　as　adding　low-cost,　high-potential　alloy　elements　such　as　N　and　Si)　to　improve　the　corrosion　wear　resistance　of　the　matrix.
