Dataset on experimental investigation of optimum carburizing temperature and holding time of bi- nano additives treatment of AISI 5130 steel

Investigation of optimum carburizing temperature and holding time on bi- nano additives treatment of AISI 5130 steel was presented in this study. AISI 5130 steel of 100 kg mass of 0.35% carbon content was buried in pulverized additives consisting of palm kernel and coconut shell using eggshell as an energizer. Four sets of 150×150×150 mm3 steel boxes packed with additives mixed at varying weight ratio of 50: 30:20 and sixty-four pieces of 20×20×5 mm3 AISI 5130 steel were case hardened using muffle furnace (2500 °C max capacity) at respective temperatures and time of 950, 1000, 1050, 1100 °C and 60, 90, 120, 180 min. The core, interface and surface hardness of the treated samples with their respective weight loss, wear volume and rate were investigated. This dataset could be used in nano-composite match mixed ratio and optimization of carburizing medium and time for any industrial used case hardened steel.

AISI 5130 steel of 100 kg mass of 0.35% carbon content was buried in pulverized additives consisting of palm kernel and coconut shell using eggshell as an energizer. Four sets of 150 Â 150 Â 150 mm 3 steel boxes packed with additives mixed at varying weight ratio of 50: 30:20 and sixty-four pieces of 20 Â 20 Â 5 mm 3 AISI 5130 steel were case hardened using muffle furnace (2500°C max capacity) at respective temperatures and time of 950, 1000, 1050, 1100°C and 60, 90, 120, 180 min. The core, interface and surface hardness of the treated samples with their respective weight loss, wear volume and rate were investigated. This dataset could be used in nano-composite match mixed ratio and optimization of carburizing medium and time for any industrial used case hardened steel. &

Value of the data
The dataset for the surface, interface and core hardness can be used to predict optimum carburizing temperature of the treated sample.
Data on the holding time of bi-nano additives treatment of AISI 5130 could be used to determine additives concentration in mix match ratio.
The data could be used to predict critical temperatures for the optimum carburizing index parameters. Also, the dataset obtained could be used in studying the heat treatment behaviour during carburization.
Data acquired for weight loss, wear volume and rate could be used to check the rate of the casecarbon index during heat treatment.

Data
The research work engaged the used of eggshell as energizer with palm kernel shell and coconut shell as carbon additives. The method can be applied as a part of the heat treatment of steel materials intended to be used to produce industrial tools and devices. Elemental compositional analyses were checked as indicated in Table 1. The dataset of the hardness values that was shown in Table 2 represents the sampling test template. Weight loss and wear volume data were recorded in Table 3 while Table 4 showed the summary of the surface, interface and core hardness of the treated sample. The values for the wear rate and average hardness of each sample were recorded in Table 5.

Experimental design, materials and methods
Bi-nano additives consisting of pulverized palm kernel and coconut shell with eggshell as an energizer were used as raw materials [1][2][3][4][5]. Steel boxes of four sets with a dimension of 150 Â 150 Â 150 mm 3 and sixty-four pieces of AISI 5130 steel (20 Â 20 Â 5 mm 3 ) were also used during the research work. The elemental composition shown in Table 1 was first carried out with spectrometer before carburization. Sixteen boxes contained four each of AISI 5130 steel (0.35% carbon) were packed with additives mixed at varying weight ratio of 50:30:20 [6][7][8][9][10]. Four set of steel boxes contained sixty pieces of AISI 5130 steel were carburized using muffle furnace (2500°C max capacity) at respective carburizing temperatures and time of 950, 1000, 1050, 1100°C and 60, 90, 120, 180 min. The sampling template of each carburizing temperature and holding time was carefully considered as indicated in Table 2 in order to obtain the optimum temperature and time at regular interval [11][12][13][14][15][16][17].  Weight loss and wear volume of each sample was investigated using Rotopol-V during machining as recorded in Table 3. The test for core, interface and surface hardness of the samples were done using hardness tester shown in Table 4 [18,19]. The values for the wear rate and average hardness of each sample were carried out and all were indicated in Table 5 [20].
