Description
本發明係有關於一種含碳化鈦矽(Ti3 SiC)化合物之高合金鑄鐵組成物及其製造方法，尤其係指一種包含有碳化鈦(TiC)、矽化鈦(Ti15 Si)以及稀土元素(Rare Earth)的高鉻合金鑄鐵，藉此，能夠提升彎曲、壓縮以及衝擊強度，並且降低體積磨耗率以延長使用壽命。The present invention relates to a high alloy cast iron composition containing titanium strontium carbide (Ti 3 SiC) compound and a method for producing the same, and particularly to a method comprising titanium carbide (TiC), titanium telluride (Ti 15 Si) and rare earth elements ( Rare Earth's high-chromium alloy cast iron, which increases bending, compression and impact strength and reduces volumetric wear to extend service life.
按，高鉻合金鑄鐵由於耐腐蝕又耐磨，因此在現代的應用係相當的廣，先前製作高鉻合金鑄鐵時，為了增加機械性質，如硬度(HRC)、壓縮強度(CS)、彎曲強度(BS)、衝擊強度(IE)以及體積磨耗率(WVL)等，通常會在高鉻合金的製備過程中加入高量鎳(Ni)元素和其他金屬元素。舉例而言，中華民國專利公告號TW I393789 B「鐵基耐腐蝕耐摩耗性合金」即揭示一種高鉻耐磨耐腐蝕合金，其包含有0.5 wt%~2.0 wt%碳(C)、2.5 wt%~4.5 wt%矽(Si)、0 wt%~10 wt%錳(Mn)、15 wt%~31 wt%鉻(Cr)、0 wt%~16 wt%鎳(Ni)、7 wt%以下的銅(Cu)以及10 wt%以下的鉬(Mo)等元素，其係為開發一種兼具耐腐蝕及耐磨耗的合金，並且改善先前技術所製成的合金因利用到大量的高價鎳(Ni)金屬，而具有成本過高之缺失。According to the high corrosion resistance and wear resistance of high chromium alloy cast iron, it is quite widely used in modern applications. In the previous production of high chromium alloy cast iron, in order to increase mechanical properties such as hardness (HRC), compressive strength (CS), bending strength (BS), impact strength (IE), and volume wear rate (WVL), etc., usually add high amounts of nickel (Ni) and other metal elements in the preparation of high chromium alloys. For example, the Republic of China Patent Publication No. TW I393789 B "Iron-based corrosion-resistant and wear-resistant alloy" discloses a high-chromium wear-resistant corrosion-resistant alloy containing 0.5 wt% to 2.0 wt% carbon (C), 2.5 wt. %~4.5 wt%矽(Si), 0 wt%~10 wt% manganese (Mn), 15 wt%~31 wt% chromium (Cr), 0 wt%~16 wt% nickel (Ni), 7 wt% or less Elemental copper (Cu) and molybdenum (Mo) of less than 10 wt%, which is an alloy that combines corrosion resistance and wear resistance, and improves the alloys produced in the prior art by utilizing a large amount of high-priced nickel (Ni) metal, with a lack of cost.
由於鎳(Ni)係屬於價格較高的金屬，因此，有許多研究都往「降低鎳(Ni)量」的方向發展，例如中華民國專利公開號TW 200831685 A揭示一種「低鎳高耐蝕性不銹鋼組成物」，其包含有0.08 wt%以下的碳(C)、16.0 wt%~20.0 wt%鉻(Cr)、4.5 wt%~8.5 wt%錳(Mn)、3.0 wt%~5.5 wt%鎳(Ni)、1.5 wt%~3.5 wt%銅(Cu)、1.0 wt%以下的矽(Si)以及0.2 wt%以下的氮(N)，係藉由降低鎳(Ni)含量，並以其他元素彌補鎳(Ni)在不鏽鋼中的角色，以使原料的成本得以降低。Since nickel (Ni) is a relatively expensive metal, many studies have progressed in the direction of "reducing the amount of nickel (Ni)". For example, the Republic of China Patent Publication No. TW 200831685 A discloses a "low nickel high corrosion resistant stainless steel". a composition comprising: 0.08 wt% or less of carbon (C), 16.0 wt% to 20.0 wt% of chromium (Cr), 4.5 wt% to 8.5 wt% of manganese (Mn), and 3.0 wt% to 5.5 wt% of nickel ( Ni), 1.5 wt% to 3.5 wt% copper (Cu), 1.0 wt% or less of niobium (Si), and 0.2 wt% or less of nitrogen (N) by reducing nickel (Ni) content and making up with other elements The role of nickel (Ni) in stainless steel is to reduce the cost of raw materials.
據上述專利可知，現有技術雖能藉由降低鎳(Ni)的含量以減低成本，卻無法達到實際捨棄鎳(Ni)以製作具有相當強度的高鉻合金鑄鐵材料，本發明人熟知鈦(Ti)元素擁有良好優異的機械性質，雖然鈦(Ti)較鎳(Ni)昂貴，但只要微量添加就有顯著的功效，係相當適合代替鎳(Ni)用於合金中，然而，鈦(Ti)的熔點相對於鎳(Ni)係較高，於製備合金時有難以溶解的困難，因此，如何讓鈦(Ti)順利熔解並成功應用於合金中便成為本發明人努力研究之方向。According to the above patent, the prior art can reduce the nickel (Ni) content to reduce the cost, but can not achieve the actual nickel (Ni) is discarded to produce a high-chromium alloy cast iron material having considerable strength. The inventors are well aware of titanium (Ti). The element has excellent mechanical properties. Although titanium (Ti) is more expensive than nickel (Ni), it has a remarkable effect as long as it is added in a small amount. It is quite suitable for replacing nickel (Ni) in the alloy. However, titanium (Ti) The melting point is higher than that of the nickel (Ni) system, and it is difficult to dissolve in the preparation of the alloy. Therefore, how to smoothly melt titanium (Ti) and successfully apply it to the alloy has become a research direction of the present inventors.
今，發明人即是鑑於上述現有之高鉻合金鑄鐵於實際實施使用時仍具有多處缺失，於是乃一本孜孜不倦之精神，並藉由其豐富專業知識及多年之實務經驗所輔佐，而加以改善，並據此研創出本發明。Nowadays, the inventor is considering that the above-mentioned existing high-chromium alloy cast iron still has many defects in practical use, so it is a tireless spirit and is supplemented by its rich professional knowledge and years of practical experience. Improvements have been made and the present invention has been developed based on this.

首先，取矽化鈦(Ti15 Si)、碳化鈦(TiC)以及鑭(La)混合均勻以形成混合材料，於真空爐進行高溫加熱至溫度約1680℃，其中矽化鈦(Ti15 Si)之熔點為1300℃，而碳化鈦(TiC)熔點需3000℃，因此矽化鈦(Ti15 Si)會先熔解，並包覆住碳化鈦(TiC)及鑭(La)，獲得一矽化鈦(Ti3 Si)以及一含有鑭(La)之碳化鈦矽(TiSiC(RE))。First, titanium nitride (Ti 15 Si), titanium carbide (TiC) and lanthanum (La) are mixed uniformly to form a mixed material, which is heated at a high temperature in a vacuum furnace to a temperature of about 1680 ° C, wherein the melting point of titanium (Ti 15 Si) It is 1300 ° C, and the melting point of titanium carbide (TiC) needs 3000 ° C, so titanium telluride (Ti 15 Si) will be melted first, and covered with titanium carbide (TiC) and lanthanum (La) to obtain a titanium telluride (Ti 3 Si) And a titanium carbide tantalum (TiSiC(RE)) containing lanthanum (La).
再者，配製一含有2.2 wt%-3.2 wt%碳(C)、22 wt%-35 wt%鉻(Cr)、0.5 wt%-3.5 wt%矽(Si)、0.3 wt%-1.0 wt%錳(Mn)、0.3 wt%-1.0 wt%鎳(Ni)、0.3 wt%-1.0 wt%銅(Cu)以及0.1 wt%-0.5 wt%鉬(Mo)的高合金鑄鐵熔湯，將矽化鈦(Ti3 Si)及含有鑭(La)之碳化鈦矽(TiSiC(RE))添加至熔湯中，固化後再接續進行熱處理程序，共需加熱三次，先以最高溫1050℃加熱約2~24小時，再以溫度710℃加熱約2~4小時，最後以溫度420℃加熱約4~12小時，完全冷卻後會凝固，即可獲得一含碳化鈦矽(Ti3 SiC)化合物之高合金鑄鐵組成物，其中具有0.1 wt%-1.2 wt%之鈦(Ti)元素，於實施過程中亦發現，鈦(Ti)含量超過1.2 wt%反而會使本發明之高合金鑄鐵強度逐漸下降，因此，鈦(Ti)元素含量0.1 wt%-1.2 wt%係為最恰當之範圍。Furthermore, the formulation contains 2.2 wt% to 3.2 wt% carbon (C), 22 wt% to 35 wt% chromium (Cr), 0.5 wt% to 3.5 wt% bismuth (Si), and 0.3 wt% to 1.0 wt% manganese. (Mn), 0.3 wt% - 1.0 wt% nickel (Ni), 0.3 wt% - 1.0 wt% copper (Cu), and 0.1 wt% - 0.5 wt% molybdenum (Mo) high alloy cast iron melt, titanium telluride ( Ti 3 Si) and Titanium carbide (TiSiC) containing lanthanum (La) are added to the melt, and after curing, the heat treatment process is continued, and a total of three heatings are required, first heating at a maximum temperature of 1050 ° C for about 2 to 24 In an hour, it is heated at a temperature of 710 ° C for about 2 to 4 hours, and finally heated at a temperature of 420 ° C for about 4 to 12 hours. After cooling, it solidifies to obtain a high alloy cast iron containing titanium strontium carbide (Ti 3 SiC) compound. The composition, which has a titanium (Ti) element of 0.1 wt% to 1.2 wt%, is also found during the implementation, and the titanium (Ti) content exceeds 1.2 wt%, which in turn causes the strength of the high alloy cast iron of the present invention to gradually decrease. The titanium (Ti) element content of 0.1 wt% to 1.2 wt% is the most suitable range.
將本發明之含碳化鈦矽(Ti3 SiC)化合物之高合金鑄鐵組成物與傳統高鉻鑄鐵(HCr)、僅添加碳化鈦(TiC)之鑄鐵、僅添加矽化鈦(TiSi)之鑄鐵以及同時添加碳化鈦與矽化鈦(TiC+TiSi)與再經過本案熱處理獲得Ti3 SiC之鑄鐵作機械性質測試，分別測試並比較洛式硬度(HRC)、壓縮強度(CS)、彎曲強度(BS)、衝擊強度(IE)以及體積磨耗率(WVL)，測試結果如表一。The high alloy cast iron composition of the titanium carbide containing titanium (Ti 3 SiC) compound of the present invention is combined with a conventional high chromium cast iron (HCr), a cast iron to which only titanium carbide (TiC) is added, a cast iron to which only titanium telluride (TiSi) is added, and The addition of titanium carbide and titanium telluride (TiC+TiSi) and the heat treatment of Ti 3 SiC obtained by heat treatment in this case were tested for mechanical properties, and the hardness (HRC), compressive strength (CS), flexural strength (BS), and hardness were tested and compared.
